It is represented as a single file on +your disk and represents a consistent snapshot of your data. + +To open your database, simply use the `bolt.Open()` function: + +```go +package main + +import ( + "log" + + "github.com/boltdb/bolt" +) + +func main() { + // Open the my.db data file in your current directory. + // It will be created if it doesn't exist. + db, err := bolt.Open("my.db", 0600, nil) + if err != nil { + log.Fatal(err) + } + defer db.Close() + + ... +} +``` + +Please note that Bolt obtains a file lock on the data file so multiple processes +cannot open the same database at the same time. Opening an already open Bolt +database will cause it to hang until the other process closes it. To prevent +an indefinite wait you can pass a timeout option to the `Open()` function: + +```go +db, err := bolt.Open("my.db", 0600, &bolt.Options{Timeout: 1 * time.Second}) +``` + + +### Transactions + +Bolt allows only one read-write transaction at a time but allows as many +read-only transactions as you want at a time. Each transaction has a consistent +view of the data as it existed when the transaction started. + +Individual transactions and all objects created from them (e.g. buckets, keys) +are not thread safe. To work with data in multiple goroutines you must start +a transaction for each one or use locking to ensure only one goroutine accesses +a transaction at a time. Creating transaction from the `DB` is thread safe. + +Read-only transactions and read-write transactions should not depend on one +another and generally shouldn't be opened simultaneously in the same goroutine. +This can cause a deadlock as the read-write transaction needs to periodically +re-map the data file but it cannot do so while a read-only transaction is open. + + +#### Read-write transactions + +To start a read-write transaction, you can use the `DB.Update()` function: + +```go +err := db.Update(func(tx *bolt.Tx) error { + ... + return nil +}) +``` + +Inside the closure, you have a consistent view of the database. You commit the +transaction by returning `nil` at the end. You can also rollback the transaction +at any point by returning an error. All database operations are allowed inside +a read-write transaction. + +Always check the return error as it will report any disk failures that can cause +your transaction to not complete. If you return an error within your closure +it will be passed through. + + +#### Read-only transactions + +To start a read-only transaction, you can use the `DB.View()` function: + +```go +err := db.View(func(tx *bolt.Tx) error { + ... + return nil +}) +``` + +You also get a consistent view of the database within this closure, however, +no mutating operations are allowed within a read-only transaction. You can only +retrieve buckets, retrieve values, and copy the database within a read-only +transaction. + + +#### Batch read-write transactions + +Each `DB.Update()` waits for disk to commit the writes. This overhead +can be minimized by combining multiple updates with the `DB.Batch()` +function: + +```go +err := db.Batch(func(tx *bolt.Tx) error { + ... + return nil +}) +``` + +Concurrent Batch calls are opportunistically combined into larger +transactions. Batch is only useful when there are multiple goroutines +calling it. + +The trade-off is that `Batch` can call the given +function multiple times, if parts of the transaction fail. The +function must be idempotent and side effects must take effect only +after a successful return from `DB.Batch()`. + +For example: don't display messages from inside the function, instead +set variables in the enclosing scope: + +```go +var id uint64 +err := db.Batch(func(tx *bolt.Tx) error { + // Find last key in bucket, decode as bigendian uint64, increment + // by one, encode back to []byte, and add new key. + ... + id = newValue + return nil +}) +if err != nil { + return ... +} +fmt.Println("Allocated ID %d", id) +``` + + +#### Managing transactions manually + +The `DB.View()` and `DB.Update()` functions are wrappers around the `DB.Begin()` +function. These helper functions will start the transaction, execute a function, +and then safely close your transaction if an error is returned. This is the +recommended way to use Bolt transactions. + +However, sometimes you may want to manually start and end your transactions. +You can use the `DB.Begin()` function directly but **please** be sure to close +the transaction. + +```go +// Start a writable transaction. +tx, err := db.Begin(true) +if err != nil { + return err +} +defer tx.Rollback() + +// Use the transaction... +_, err := tx.CreateBucket([]byte("MyBucket")) +if err != nil { + return err +} + +// Commit the transaction and check for error. +if err := tx.Commit(); err != nil { + return err +} +``` + +The first argument to `DB.Begin()` is a boolean stating if the transaction +should be writable. + + +### Using buckets + +Buckets are collections of key/value pairs within the database. All keys in a +bucket must be unique. You can create a bucket using the `DB.CreateBucket()` +function: + +```go +db.Update(func(tx *bolt.Tx) error { + b, err := tx.CreateBucket([]byte("MyBucket")) + if err != nil { + return fmt.Errorf("create bucket: %s", err) + } + return nil +}) +``` + +You can also create a bucket only if it doesn't exist by using the +`Tx.CreateBucketIfNotExists()` function. It's a common pattern to call this +function for all your top-level buckets after you open your database so you can +guarantee that they exist for future transactions. + +To delete a bucket, simply call the `Tx.DeleteBucket()` function. + + +### Using key/value pairs + +To save a key/value pair to a bucket, use the `Bucket.Put()` function: + +```go +db.Update(func(tx *bolt.Tx) error { + b := tx.Bucket([]byte("MyBucket")) + err := b.Put([]byte("answer"), []byte("42")) + return err +}) +``` + +This will set the value of the `"answer"` key to `"42"` in the `MyBucket` +bucket. To retrieve this value, we can use the `Bucket.Get()` function: + +```go +db.View(func(tx *bolt.Tx) error { + b := tx.Bucket([]byte("MyBucket")) + v := b.Get([]byte("answer")) + fmt.Printf("The answer is: %s\n", v) + return nil +}) +``` + +The `Get()` function does not return an error because its operation is +guaranteed to work (unless there is some kind of system failure). If the key +exists then it will return its byte slice value. If it doesn't exist then it +will return `nil`. It's important to note that you can have a zero-length value +set to a key which is different than the key not existing. + +Use the `Bucket.Delete()` function to delete a key from the bucket. + +Please note that values returned from `Get()` are only valid while the +transaction is open. If you need to use a value outside of the transaction +then you must use `copy()` to copy it to another byte slice. + + +### Autoincrementing integer for the bucket +By using the `NextSequence()` function, you can let Bolt determine a sequence +which can be used as the unique identifier for your key/value pairs. See the +example below. + +```go +// CreateUser saves u to the store. The new user ID is set on u once the data is persisted. +func (s *Store) CreateUser(u *User) error { + return s.db.Update(func(tx *bolt.Tx) error { + // Retrieve the users bucket. + // This should be created when the DB is first opened. + b := tx.Bucket([]byte("users")) + + // Generate ID for the user. + // This returns an error only if the Tx is closed or not writeable. + // That can't happen in an Update() call so I ignore the error check. + id, _ := b.NextSequence() + u.ID = int(id) + + // Marshal user data into bytes. + buf, err := json.Marshal(u) + if err != nil { + return err + } + + // Persist bytes to users bucket. + return b.Put(itob(u.ID), buf) + }) +} + +// itob returns an 8-byte big endian representation of v. +func itob(v int) []byte { + b := make([]byte, 8) + binary.BigEndian.PutUint64(b, uint64(v)) + return b +} + +type User struct { + ID int + ... +} +``` + +### Iterating over keys + +Bolt stores its keys in byte-sorted order within a bucket. This makes sequential +iteration over these keys extremely fast. To iterate over keys we'll use a +`Cursor`: + +```go +db.View(func(tx *bolt.Tx) error { + // Assume bucket exists and has keys + b := tx.Bucket([]byte("MyBucket")) + + c := b.Cursor() + + for k, v := c.First(); k != nil; k, v = c.Next() { + fmt.Printf("key=%s, value=%s\n", k, v) + } + + return nil +}) +``` + +The cursor allows you to move to a specific point in the list of keys and move +forward or backward through the keys one at a time. + +The following functions are available on the cursor: + +``` +First() Move to the first key. +Last() Move to the last key. +Seek() Move to a specific key. +Next() Move to the next key. +Prev() Move to the previous key. +``` + +Each of those functions has a return signature of `(key []byte, value []byte)`. +When you have iterated to the end of the cursor then `Next()` will return a +`nil` key. You must seek to a position using `First()`, `Last()`, or `Seek()` +before calling `Next()` or `Prev()`. If you do not seek to a position then +these functions will return a `nil` key. + +During iteration, if the key is non-`nil` but the value is `nil`, that means +the key refers to a bucket rather than a value. Use `Bucket.Bucket()` to +access the sub-bucket. + + +#### Prefix scans + +To iterate over a key prefix, you can combine `Seek()` and `bytes.HasPrefix()`: + +```go +db.View(func(tx *bolt.Tx) error { + // Assume bucket exists and has keys + c := tx.Bucket([]byte("MyBucket")).Cursor() + + prefix := []byte("1234") + for k, v := c.Seek(prefix); bytes.HasPrefix(k, prefix); k, v = c.Next() { + fmt.Printf("key=%s, value=%s\n", k, v) + } + + return nil +}) +``` + +#### Range scans + +Another common use case is scanning over a range such as a time range. If you +use a sortable time encoding such as RFC3339 then you can query a specific +date range like this: + +```go +db.View(func(tx *bolt.Tx) error { + // Assume our events bucket exists and has RFC3339 encoded time keys. + c := tx.Bucket([]byte("Events")).Cursor() + + // Our time range spans the 90's decade. + min := []byte("1990-01-01T00:00:00Z") + max := []byte("2000-01-01T00:00:00Z") + + // Iterate over the 90's. + for k, v := c.Seek(min); k != nil && bytes.Compare(k, max) <= 0; k, v = c.Next() { + fmt.Printf("%s: %s\n", k, v) + } + + return nil +}) +``` + +Note that, while RFC3339 is sortable, the Golang implementation of RFC3339Nano does not use a fixed number of digits after the decimal point and is therefore not sortable. + + +#### ForEach() + +You can also use the function `ForEach()` if you know you'll be iterating over +all the keys in a bucket: + +```go +db.View(func(tx *bolt.Tx) error { + // Assume bucket exists and has keys + b := tx.Bucket([]byte("MyBucket")) + + b.ForEach(func(k, v []byte) error { + fmt.Printf("key=%s, value=%s\n", k, v) + return nil + }) + return nil +}) +``` + +Please note that keys and values in `ForEach()` are only valid while +the transaction is open. If you need to use a key or value outside of +the transaction, you must use `copy()` to copy it to another byte +slice. + +### Nested buckets + +You can also store a bucket in a key to create nested buckets. The API is the +same as the bucket management API on the `DB` object: + +```go +func (*Bucket) CreateBucket(key []byte) (*Bucket, error) +func (*Bucket) CreateBucketIfNotExists(key []byte) (*Bucket, error) +func (*Bucket) DeleteBucket(key []byte) error +``` + +Say you had a multi-tenant application where the root level bucket was the account bucket. Inside of this bucket was a sequence of accounts which themselves are buckets. And inside the sequence bucket you could have many buckets pertaining to the Account itself (Users, Notes, etc) isolating the information into logical groupings. + +```go + +// createUser creates a new user in the given account. +func createUser(accountID int, u *User) error { + // Start the transaction. + tx, err := db.Begin(true) + if err != nil { + return err + } + defer tx.Rollback() + + // Retrieve the root bucket for the account. + // Assume this has already been created when the account was set up. + root := tx.Bucket([]byte(strconv.FormatUint(accountID, 10))) + + // Setup the users bucket. + bkt, err := root.CreateBucketIfNotExists([]byte("USERS")) + if err != nil { + return err + } + + // Generate an ID for the new user. + userID, err := bkt.NextSequence() + if err != nil { + return err + } + u.ID = userID + + // Marshal and save the encoded user. + if buf, err := json.Marshal(u); err != nil { + return err + } else if err := bkt.Put([]byte(strconv.FormatUint(u.ID, 10)), buf); err != nil { + return err + } + + // Commit the transaction. + if err := tx.Commit(); err != nil { + return err + } + + return nil +} + +``` + + + + +### Database backups + +Bolt is a single file so it's easy to backup. You can use the `Tx.WriteTo()` +function to write a consistent view of the database to a writer. If you call +this from a read-only transaction, it will perform a hot backup and not block +your other database reads and writes. + +By default, it will use a regular file handle which will utilize the operating +system's page cache. See the [`Tx`](https://godoc.org/github.com/boltdb/bolt#Tx) +documentation for information about optimizing for larger-than-RAM datasets. + +One common use case is to backup over HTTP so you can use tools like `cURL` to +do database backups: + +```go +func BackupHandleFunc(w http.ResponseWriter, req *http.Request) { + err := db.View(func(tx *bolt.Tx) error { + w.Header().Set("Content-Type", "application/octet-stream") + w.Header().Set("Content-Disposition", `attachment; filename="my.db"`) + w.Header().Set("Content-Length", strconv.Itoa(int(tx.Size()))) + _, err := tx.WriteTo(w) + return err + }) + if err != nil { + http.Error(w, err.Error(), http.StatusInternalServerError) + } +} +``` + +Then you can backup using this command: + +```sh +$ curl http://localhost/backup > my.db +``` + +Or you can open your browser to `http://localhost/backup` and it will download +automatically. + +If you want to backup to another file you can use the `Tx.CopyFile()` helper +function. + + +### Statistics + +The database keeps a running count of many of the internal operations it +performs so you can better understand what's going on. By grabbing a snapshot +of these stats at two points in time we can see what operations were performed +in that time range. + +For example, we could start a goroutine to log stats every 10 seconds: + +```go +go func() { + // Grab the initial stats. + prev := db.Stats() + + for { + // Wait for 10s. + time.Sleep(10 * time.Second) + + // Grab the current stats and diff them. + stats := db.Stats() + diff := stats.Sub(&prev) + + // Encode stats to JSON and print to STDERR. + json.NewEncoder(os.Stderr).Encode(diff) + + // Save stats for the next loop. + prev = stats + } +}() +``` + +It's also useful to pipe these stats to a service such as statsd for monitoring +or to provide an HTTP endpoint that will perform a fixed-length sample. + + +### Read-Only Mode + +Sometimes it is useful to create a shared, read-only Bolt database. To this, +set the `Options.ReadOnly` flag when opening your database. Read-only mode +uses a shared lock to allow multiple processes to read from the database but +it will block any processes from opening the database in read-write mode. + +```go +db, err := bolt.Open("my.db", 0666, &bolt.Options{ReadOnly: true}) +if err != nil { + log.Fatal(err) +} +``` + +### Mobile Use (iOS/Android) + +Bolt is able to run on mobile devices by leveraging the binding feature of the +[gomobile](https://github.com/golang/mobile) tool. Create a struct that will +contain your database logic and a reference to a `*bolt.DB` with a initializing +constructor that takes in a filepath where the database file will be stored. +Neither Android nor iOS require extra permissions or cleanup from using this method. + +```go +func NewBoltDB(filepath string) *BoltDB { + db, err := bolt.Open(filepath+"/demo.db", 0600, nil) + if err != nil { + log.Fatal(err) + } + + return &BoltDB{db} +} + +type BoltDB struct { + db *bolt.DB + ... +} + +func (b *BoltDB) Path() string { + return b.db.Path() +} + +func (b *BoltDB) Close() { + b.db.Close() +} +``` + +Database logic should be defined as methods on this wrapper struct. + +To initialize this struct from the native language (both platforms now sync +their local storage to the cloud. These snippets disable that functionality for the +database file): + +#### Android + +```java +String path; +if (android.os.Build.VERSION.SDK_INT >=android.os.Build.VERSION_CODES.LOLLIPOP){ + path = getNoBackupFilesDir().getAbsolutePath(); +} else{ + path = getFilesDir().getAbsolutePath(); +} +Boltmobiledemo.BoltDB boltDB = Boltmobiledemo.NewBoltDB(path) +``` + +#### iOS + +```objc +- (void)demo { + NSString* path = [NSSearchPathForDirectoriesInDomains(NSLibraryDirectory, + NSUserDomainMask, + YES) objectAtIndex:0]; + GoBoltmobiledemoBoltDB * demo = GoBoltmobiledemoNewBoltDB(path); + [self addSkipBackupAttributeToItemAtPath:demo.path]; + //Some DB Logic would go here + [demo close]; +} + +- (BOOL)addSkipBackupAttributeToItemAtPath:(NSString *) filePathString +{ + NSURL* URL= [NSURL fileURLWithPath: filePathString]; + assert([[NSFileManager defaultManager] fileExistsAtPath: [URL path]]); + + NSError *error = nil; + BOOL success = [URL setResourceValue: [NSNumber numberWithBool: YES] + forKey: NSURLIsExcludedFromBackupKey error: &error]; + if(!success){ + NSLog(@"Error excluding %@ from backup %@", [URL lastPathComponent], error); + } + return success; +} + +``` + +## Resources + +For more information on getting started with Bolt, check out the following articles: + +* [Intro to BoltDB: Painless Performant Persistence](http://npf.io/2014/07/intro-to-boltdb-painless-performant-persistence/) by [Nate Finch](https://github.com/natefinch). +* [Bolt -- an embedded key/value database for Go](https://www.progville.com/go/bolt-embedded-db-golang/) by Progville + + +## Comparison with other databases + +### Postgres, MySQL, & other relational databases + +Relational databases structure data into rows and are only accessible through +the use of SQL. This approach provides flexibility in how you store and query +your data but also incurs overhead in parsing and planning SQL statements. Bolt +accesses all data by a byte slice key. This makes Bolt fast to read and write +data by key but provides no built-in support for joining values together. + +Most relational databases (with the exception of SQLite) are standalone servers +that run separately from your application. This gives your systems +flexibility to connect multiple application servers to a single database +server but also adds overhead in serializing and transporting data over the +network. Bolt runs as a library included in your application so all data access +has to go through your application's process. This brings data closer to your +application but limits multi-process access to the data. + + +### LevelDB, RocksDB + +LevelDB and its derivatives (RocksDB, HyperLevelDB) are similar to Bolt in that +they are libraries bundled into the application, however, their underlying +structure is a log-structured merge-tree (LSM tree). An LSM tree optimizes +random writes by using a write ahead log and multi-tiered, sorted files called +SSTables. Bolt uses a B+tree internally and only a single file. Both approaches +have trade-offs. + +If you require a high random write throughput (>10,000 w/sec) or you need to use +spinning disks then LevelDB could be a good choice. If your application is +read-heavy or does a lot of range scans then Bolt could be a good choice. + +One other important consideration is that LevelDB does not have transactions. +It supports batch writing of key/values pairs and it supports read snapshots +but it will not give you the ability to do a compare-and-swap operation safely. +Bolt supports fully serializable ACID transactions. + + +### LMDB + +Bolt was originally a port of LMDB so it is architecturally similar. Both use +a B+tree, have ACID semantics with fully serializable transactions, and support +lock-free MVCC using a single writer and multiple readers. + +The two projects have somewhat diverged. LMDB heavily focuses on raw performance +while Bolt has focused on simplicity and ease of use. For example, LMDB allows +several unsafe actions such as direct writes for the sake of performance. Bolt +opts to disallow actions which can leave the database in a corrupted state. The +only exception to this in Bolt is `DB.NoSync`. + +There are also a few differences in API. LMDB requires a maximum mmap size when +opening an `mdb_env` whereas Bolt will handle incremental mmap resizing +automatically. LMDB overloads the getter and setter functions with multiple +flags whereas Bolt splits these specialized cases into their own functions. + + +## Caveats & Limitations + +It's important to pick the right tool for the job and Bolt is no exception. +Here are a few things to note when evaluating and using Bolt: + +* Bolt is good for read intensive workloads. Sequential write performance is + also fast but random writes can be slow. You can use `DB.Batch()` or add a + write-ahead log to help mitigate this issue. + +* Bolt uses a B+tree internally so there can be a lot of random page access. + SSDs provide a significant performance boost over spinning disks. + +* Try to avoid long running read transactions. Bolt uses copy-on-write so + old pages cannot be reclaimed while an old transaction is using them. + +* Byte slices returned from Bolt are only valid during a transaction. Once the + transaction has been committed or rolled back then the memory they point to + can be reused by a new page or can be unmapped from virtual memory and you'll + see an `unexpected fault address` panic when accessing it. + +* Be careful when using `Bucket.FillPercent`. Setting a high fill percent for + buckets that have random inserts will cause your database to have very poor + page utilization. + +* Use larger buckets in general. Smaller buckets causes poor page utilization + once they become larger than the page size (typically 4KB). + +* Bulk loading a lot of random writes into a new bucket can be slow as the + page will not split until the transaction is committed. Randomly inserting + more than 100,000 key/value pairs into a single new bucket in a single + transaction is not advised. + +* Bolt uses a memory-mapped file so the underlying operating system handles the + caching of the data. Typically, the OS will cache as much of the file as it + can in memory and will release memory as needed to other processes. This means + that Bolt can show very high memory usage when working with large databases. + However, this is expected and the OS will release memory as needed. Bolt can + handle databases much larger than the available physical RAM, provided its + memory-map fits in the process virtual address space. It may be problematic + on 32-bits systems. + +* The data structures in the Bolt database are memory mapped so the data file + will be endian specific. This means that you cannot copy a Bolt file from a + little endian machine to a big endian machine and have it work. For most + users this is not a concern since most modern CPUs are little endian. + +* Because of the way pages are laid out on disk, Bolt cannot truncate data files + and return free pages back to the disk. Instead, Bolt maintains a free list + of unused pages within its data file. These free pages can be reused by later + transactions. This works well for many use cases as databases generally tend + to grow. However, it's important to note that deleting large chunks of data + will not allow you to reclaim that space on disk. + + For more information on page allocation, [see this comment][page-allocation]. + +[page-allocation]: https://github.com/boltdb/bolt/issues/308#issuecomment-74811638 + + +## Reading the Source + +Bolt is a relatively small code base (<3KLOC) for an embedded, serializable, +transactional key/value database so it can be a good starting point for people +interested in how databases work. + +The best places to start are the main entry points into Bolt: + +- `Open()` - Initializes the reference to the database. It's responsible for + creating the database if it doesn't exist, obtaining an exclusive lock on the + file, reading the meta pages, & memory-mapping the file. + +- `DB.Begin()` - Starts a read-only or read-write transaction depending on the + value of the `writable` argument. This requires briefly obtaining the "meta" + lock to keep track of open transactions. Only one read-write transaction can + exist at a time so the "rwlock" is acquired during the life of a read-write + transaction. + +- `Bucket.Put()` - Writes a key/value pair into a bucket. After validating the + arguments, a cursor is used to traverse the B+tree to the page and position + where they key & value will be written. Once the position is found, the bucket + materializes the underlying page and the page's parent pages into memory as + "nodes". These nodes are where mutations occur during read-write transactions. + These changes get flushed to disk during commit. + +- `Bucket.Get()` - Retrieves a key/value pair from a bucket. This uses a cursor + to move to the page & position of a key/value pair. During a read-only + transaction, the key and value data is returned as a direct reference to the + underlying mmap file so there's no allocation overhead. For read-write + transactions, this data may reference the mmap file or one of the in-memory + node values. + +- `Cursor` - This object is simply for traversing the B+tree of on-disk pages + or in-memory nodes. It can seek to a specific key, move to the first or last + value, or it can move forward or backward. The cursor handles the movement up + and down the B+tree transparently to the end user. + +- `Tx.Commit()` - Converts the in-memory dirty nodes and the list of free pages + into pages to be written to disk. Writing to disk then occurs in two phases. + First, the dirty pages are written to disk and an `fsync()` occurs. Second, a + new meta page with an incremented transaction ID is written and another + `fsync()` occurs. This two phase write ensures that partially written data + pages are ignored in the event of a crash since the meta page pointing to them + is never written. Partially written meta pages are invalidated because they + are written with a checksum. + +If you have additional notes that could be helpful for others, please submit +them via pull request. + + +## Other Projects Using Bolt + +Below is a list of public, open source projects that use Bolt: + +* [BoltDbWeb](https://github.com/evnix/boltdbweb) - A web based GUI for BoltDB files. +* [Operation Go: A Routine Mission](http://gocode.io) - An online programming game for Golang using Bolt for user accounts and a leaderboard. +* [Bazil](https://bazil.org/) - A file system that lets your data reside where it is most convenient for it to reside. +* [DVID](https://github.com/janelia-flyem/dvid) - Added Bolt as optional storage engine and testing it against Basho-tuned leveldb. +* [Skybox Analytics](https://github.com/skybox/skybox) - A standalone funnel analysis tool for web analytics. +* [Scuttlebutt](https://github.com/benbjohnson/scuttlebutt) - Uses Bolt to store and process all Twitter mentions of GitHub projects. +* [Wiki](https://github.com/peterhellberg/wiki) - A tiny wiki using Goji, BoltDB and Blackfriday. +* [ChainStore](https://github.com/pressly/chainstore) - Simple key-value interface to a variety of storage engines organized as a chain of operations. +* [MetricBase](https://github.com/msiebuhr/MetricBase) - Single-binary version of Graphite. +* [Gitchain](https://github.com/gitchain/gitchain) - Decentralized, peer-to-peer Git repositories aka "Git meets Bitcoin". +* [event-shuttle](https://github.com/sclasen/event-shuttle) - A Unix system service to collect and reliably deliver messages to Kafka. +* [ipxed](https://github.com/kelseyhightower/ipxed) - Web interface and api for ipxed. +* [BoltStore](https://github.com/yosssi/boltstore) - Session store using Bolt. +* [photosite/session](https://godoc.org/bitbucket.org/kardianos/photosite/session) - Sessions for a photo viewing site. +* [LedisDB](https://github.com/siddontang/ledisdb) - A high performance NoSQL, using Bolt as optional storage. +* [ipLocator](https://github.com/AndreasBriese/ipLocator) - A fast ip-geo-location-server using bolt with bloom filters. +* [cayley](https://github.com/google/cayley) - Cayley is an open-source graph database using Bolt as optional backend. +* [bleve](http://www.blevesearch.com/) - A pure Go search engine similar to ElasticSearch that uses Bolt as the default storage backend. +* [tentacool](https://github.com/optiflows/tentacool) - REST api server to manage system stuff (IP, DNS, Gateway...) on a linux server. +* [Seaweed File System](https://github.com/chrislusf/seaweedfs) - Highly scalable distributed key~file system with O(1) disk read. +* [InfluxDB](https://influxdata.com) - Scalable datastore for metrics, events, and real-time analytics. +* [Freehold](http://tshannon.bitbucket.org/freehold/) - An open, secure, and lightweight platform for your files and data. +* [Prometheus Annotation Server](https://github.com/oliver006/prom_annotation_server) - Annotation server for PromDash & Prometheus service monitoring system. +* [Consul](https://github.com/hashicorp/consul) - Consul is service discovery and configuration made easy.

The DB is +a collection of buckets and is represented by a single file on disk. A bucket is +a collection of unique keys that are associated with values. + +Transactions provide either read-only or read-write access to the database. +Read-only transactions can retrieve key/value pairs and can use Cursors to +iterate over the dataset sequentially. Read-write transactions can create and +delete buckets and can insert and remove keys.

This is because easyjson code generation +invokes `go run` on a temporary file (an approach to code generation borrowed +from [ffjson](https://github.com/pquerna/ffjson)). + +## Options +```txt +Usage of easyjson: + -all + generate marshaler/unmarshalers for all structs in a file + -build_tags string + build tags to add to generated file + -leave_temps + do not delete temporary files + -no_std_marshalers + don't generate MarshalJSON/UnmarshalJSON funcs + -noformat + do not run 'gofmt -w' on output file + -omit_empty + omit empty fields by default + -output_filename string + specify the filename of the output + -pkg + process the whole package instead of just the given file + -snake_case + use snake_case names instead of CamelCase by default + -stubs + only generate stubs for marshaler/unmarshaler funcs +``` + +Using `-all` will generate marshalers/unmarshalers for all Go structs in the +file. If `-all` is not provided, then only those structs whose preceeding +comment starts with `easyjson:json` will have marshalers/unmarshalers +generated. For example: + +```go +//easyjson:json +struct A{} +``` + +Additional option notes: + +* `-snake_case` tells easyjson to generate snake\_case field names by default + (unless overridden by a field tag). The CamelCase to snake\_case conversion + algorithm should work in most cases (ie, HTTPVersion will be converted to + "http_version"). + +* `-build_tags` will add the specified build tags to generated Go sources. + +## Generated Marshaler/Unmarshaler Funcs + +For Go struct types, easyjson generates the funcs `MarshalEasyJSON` / +`UnmarshalEasyJSON` for marshaling/unmarshaling JSON. In turn, these satisify +the `easyjson.Marshaler` and `easyjson.Unmarshaler` interfaces and when used in +conjunction with `easyjson.Marshal` / `easyjson.Unmarshal` avoid unnecessary +reflection / type assertions during marshaling/unmarshaling to/from JSON for Go +structs. + +easyjson also generates `MarshalJSON` and `UnmarshalJSON` funcs for Go struct +types compatible with the standard `json.Marshaler` and `json.Unmarshaler` +interfaces. Please be aware that using the standard `json.Marshal` / +`json.Unmarshal` for marshaling/unmarshaling will incur a significant +performance penalty when compared to using `easyjson.Marshal` / +`easyjson.Unmarshal`. + +Additionally, easyjson exposes utility funcs that use the `MarshalEasyJSON` and +`UnmarshalEasyJSON` for marshaling/unmarshaling to and from standard readers +and writers. For example, easyjson provides `easyjson.MarshalToHTTPResponseWriter` +which marshals to the standard `http.ResponseWriter`. Please see the [GoDoc +listing](https://godoc.org/github.com/mailru/easyjson) for the full listing of +utility funcs that are available. + +## Controlling easyjson Marshaling and Unmarshaling Behavior + +Go types can provide their own `MarshalEasyJSON` and `UnmarshalEasyJSON` funcs +that satisify the `easyjson.Marshaler` / `easyjson.Unmarshaler` interfaces. +These will be used by `easyjson.Marshal` and `easyjson.Unmarshal` when defined +for a Go type. + +Go types can also satisify the `easyjson.Optional` interface, which allows the +type to define its own `omitempty` logic. + +## Type Wrappers + +easyjson provides additional type wrappers defined in the `easyjson/opt` +package. These wrap the standard Go primitives and in turn satisify the +easyjson interfaces. + +The `easyjson/opt` type wrappers are useful when needing to distinguish between +a missing value and/or when needing to specifying a default value. Type +wrappers allow easyjson to avoid additional pointers and heap allocations and +can significantly increase performance when used properly. + +## Memory Pooling + +easyjson uses a buffer pool that allocates data in increasing chunks from 128 +to 32768 bytes. Chunks of 512 bytes and larger will be reused with the help of +`sync.Pool`. The maximum size of a chunk is bounded to reduce redundant memory +allocation and to allow larger reusable buffers. + +easyjson's custom allocation buffer pool is defined in the `easyjson/buffer` +package, and the default behavior pool behavior can be modified (if necessary) +through a call to `buffer.Init()` prior to any marshaling or unmarshaling. +Please see the [GoDoc listing](https://godoc.org/github.com/mailru/easyjson/buffer) +for more information. + +## Issues, Notes, and Limitations + +* easyjson is still early in its development. As such, there are likely to be + bugs and missing features when compared to `encoding/json`. In the case of a + missing feature or bug, please create a GitHub issue. Pull requests are + welcome! + +* Unlike `encoding/json`, object keys are case-sensitive. Case-insensitive + matching is not currently provided due to the significant performance hit + when doing case-insensitive key matching. In the future, case-insensitive + object key matching may be provided via an option to the generator. + +* easyjson makes use of `unsafe`, which simplifies the code and + provides significant performance benefits by allowing no-copy + conversion from `[]byte` to `string`. That said, `unsafe` is used + only when unmarshaling and parsing JSON, and any `unsafe` operations + / memory allocations done will be safely deallocated by + easyjson. Set the build tag `easyjson_nounsafe` to compile it + without `unsafe`. + +* easyjson is compatible with Google App Engine. The `appengine` build + tag (set by App Engine's environment) will automatically disable the + use of `unsafe`, which is not allowed in App Engine's Standard + Environment. Note that the use with App Engine is still experimental. + +* Floats are formatted using the default precision from Go's `strconv` package. + As such, easyjson will not correctly handle high precision floats when + marshaling/unmarshaling JSON. Note, however, that there are very few/limited + uses where this behavior is not sufficient for general use. That said, a + different package may be needed if precise marshaling/unmarshaling of high + precision floats to/from JSON is required. + +* While unmarshaling, the JSON parser does the minimal amount of work needed to + skip over unmatching parens, and as such full validation is not done for the + entire JSON value being unmarshaled/parsed. + +* Currently there is no true streaming support for encoding/decoding as + typically for many uses/protocols the final, marshaled length of the JSON + needs to be known prior to sending the data. Currently this is not possible + with easyjson's architecture. + +## Benchmarks + +Most benchmarks were done using the example +[13kB example JSON](https://dev.twitter.com/rest/reference/get/search/tweets) +(9k after eliminating whitespace). This example is similar to real-world data, +is well-structured, and contains a healthy variety of different types, making +it ideal for JSON serialization benchmarks. + +Note: + +* For small request benchmarks, an 80 byte portion of the above example was + used. + +* For large request marshaling benchmarks, a struct containing 50 regular + samples was used, making a ~500kB output JSON. + +* Benchmarks are showing the results of easyjson's default behaviour, + which makes use of `unsafe`. + +Benchmarks are available in the repository and can be run by invoking `make`. + +### easyjson vs. encoding/json + +easyjson is roughly 5-6 times faster than the standard `encoding/json` for +unmarshaling, and 3-4 times faster for non-concurrent marshaling. Concurrent +marshaling is 6-7x faster if marshaling to a writer. + +### easyjson vs. ffjson + +easyjson uses the same approach for JSON marshaling as +[ffjson](https://github.com/pquerna/ffjson), but takes a significantly +different approach to lexing and parsing JSON during unmarshaling. This means +easyjson is roughly 2-3x faster for unmarshaling and 1.5-2x faster for +non-concurrent unmarshaling. + +As of this writing, `ffjson` seems to have issues when used concurrently: +specifically, large request pooling hurts `ffjson`'s performance and causes +scalability issues. These issues with `ffjson` can likely be fixed, but as of +writing remain outstanding/known issues with `ffjson`. + +easyjson and `ffjson` have similar performance for small requests, however +easyjson outperforms `ffjson` by roughly 2-5x times for large requests when +used with a writer. + +### easyjson vs. go/codec + +[go/codec](https://github.com/ugorji/go) provides +compile-time helpers for JSON generation. In this case, helpers do not work +like marshalers as they are encoding-independent. + +easyjson is generally 2x faster than `go/codec` for non-concurrent benchmarks +and about 3x faster for concurrent encoding (without marshaling to a writer). + +In an attempt to measure marshaling performance of `go/codec` (as opposed to +allocations/memcpy/writer interface invocations), a benchmark was done with +resetting length of a byte slice rather than resetting the whole slice to nil. +However, the optimization in this exact form may not be applicable in practice, +since the memory is not freed between marshaling operations. + +### easyjson vs 'ujson' python module + +[ujson](https://github.com/esnme/ultrajson) is using C code for parsing, so it +is interesting to see how plain golang compares to that. It is imporant to note +that the resulting object for python is slower to access, since the library +parses JSON object into dictionaries. + +easyjson is slightly faster for unmarshaling and 2-3x faster than `ujson` for +marshaling. + +### Benchmark Results + +`ffjson` results are from February 4th, 2016, using the latest `ffjson` and go1.6. +`go/codec` results are from March 4th, 2016, using the latest `go/codec` and go1.6. + +#### Unmarshaling + +| lib | json size | MB/s | allocs/op | B/op | +|:---------|:----------|-----:|----------:|------:| +| standard | regular | 22 | 218 | 10229 |
