Change history

March 31 2015 : v1.4.2

Maintenance release.

  • Improvements

    • Replace channel-based queue system with a lock-based algorithm.
    • Marshaller now supports arrays of arbitrary types.
    • Client.GetObject() now returns an error when the object is not found.
    • Partition calculation uses a trick that is twice as fast.

  • Improvements

    • Unpacking BLOBs resulted in returning references to pooled buffers. Now copies are returned.

March 12 2015 : v1.4.1

This is a minor release to help improve the compatibility of the client on Mac OS, and to make cross compilation easier.

  • Improvements

    • Node validator won't call net.HostLookup if an IP is passed as a seed to it.

Feb 17 2015 : v1.4.0

This is a major release, and makes using the client much easier to develop applications.

  • New Features

    • Added Marshalling Support for Put and Get operations. Refer to Marshalling Test to see how to take advantage. Same functionality for other APIs will follow soon. Example:
    type SomeStruct struct {
  A    int            `as:"a"`  // alias the field to myself
  Self *SomeStruct    `as:"-"`  // will not persist the field
}

type OtherStruct struct {
  i interface{}
  OtherObject *OtherStruct
}

obj := &OtherStruct {
  i: 15,
  OtherObject: OtherStruct {A: 18},
}

key, _ := as.NewKey("ns", "set", value)
err := client.PutObject(nil, key, obj)
// handle error here

rObj := &OtherStruct{}
err = client.GetObject(nil, key, rObj)
    • Added Recordset.Results(). Consumers of a recordset do not have to implement a select anymore. Instead of:
    recordset, err := client.ScanAll(...)
L:
for {
  select {
  case r := <-recordset.Record:
    if r == nil {
      break L
    }
    // process record here
  case e := <-recordset.Errors:
    // handle error here
  }
}

    one should only range on recordset.Results():

    recordset, err := client.ScanAll(...)
for res := range recordset.Results() {
  if res.Err != nil {
    // handle error here
  } else {
    // process record here
    fmt.Println(res.Record.Bins)
  }
}

    Use of the old pattern is discouraged and deprecated, and direct access to recordset.Records and recordset.Errors will be removed in a future release.

  • Improvements

    • Custom Types are now allowed as bin values.

Jan 26 2015 : v1.3.1

  • Improvements

    • Removed dependency on unsafe package.

Jan 20 2015 : v1.3.0

  • Breaking Changes

    • Removed Record.Duplicates and GenerationPolicy/DUPLICATE

  • New Features

    • Added Security Features: Please consult Security Docs on Aerospike website.

      • ClientPolicy.User, ClientPolicy.Password
      • Client.CreateUser(), Client.DropUser(), Client.ChangePassword()
      • Client.GrantRoles(), Client.RevokeRoles(), Client.ReplaceRoles()
      • Client.QueryUser(), Client.QueryUsers

    • Added Client.QueryNode()

    • Added ClientPolicy.TendInterval

  • Improvements

    • Cleaned up Scan/Query/Recordset concurrent code

  • Fixes

    • Fixed a bug in tools/cli/cli.go.

    • Fixed a bug when GetHeaderOp() would always translate into GetOp()

Dec 29 2014: v1.2.0

  • New Features

    • Added NewKeyWithDigest() method. You can now create keys with custom digests, or only using digests without knowing the original value. (Useful when you are getting back results with Query and Scan)

Dec 22 2014

  • New Features

    • Added ConsistencyLevel to BasePolicy.

    • Added CommitLevel to WritePolicy.

    • Added LargeList.Range and LargeList.RangeThenFilter methods.

    • Added LargeMap.Exists method.

  • Improvements

    • We use a pooled XORShift RNG to produce random numbers in the client. It is FAST.

Dec 19 2014

  • Fixes

    • Record.Expiration wasn't converted to TTL values on Client.BatchGet, Client.Scan and Client.Query.

Dec 10 2014

  • Fixes:

    • Fixed issue when the size of key field would not be estimated correctly when WritePolicy.SendKey was set.

Nov 27 2014

Major Performance Enhancements. Minor new features and fixes.

  • Improvements

    • Go client is much faster and more memory efficient now. In some workloads, it competes and wins against C and Java clients.

    • Complex objects are now de/serialized much faster.

  • New Features

    • Added Default Policies for Client object. Instead of creating a new policy when the passed policy is nil, default policies will be used.

Nov 24 2014

  • Fixes:

    • Fixed issue when WritePolicy.SendKey = true was not respected in Touch() and Operate()

Nov 22 2014

Hotfix in unpacker. Update strongly recommended for everyone using Complex objects, LDTs and UDFs.

  • Fixes:

    • When Blob, ByteArray or String size has a bit sign set, unpacker reads it wrong. Note: This bug only affects unpacking of these objects. Packing was unaffected, and data in the database is valid.

Nov 2 2014

Minor, but very impoortant fix.

  • Fixes:

    • Node selection in partition map was flawed on first refresh.

  • Incompatible changes:

    • Expiration and Generation in WritePolicy are now int32
    • TaskId in Statement is now always set in the client, and is int64

  • New Features:

    • float32, float64 and bool are now supported in map and array types

Oct 15 2014 (Beta 2)

  • Hot fix:

    • Fixed pack/unpack for uint64

Aug 20 2014 (Beta 1)

Major changes and improvements.

  • New Features:

    • Added client.Query()
    • Added client.ScanNode()/All()
    • Added client.Operate()
    • Added client.CreateIndex()
    • Added client.DropIndex()
    • Added client.RegisterUDF()
    • Added client.RegisterUDFFromFile()
    • Added client.Execute()
    • Added client.ExecuteUDF()
    • Added client.BatchGet()
    • Added client.BatchGetHeader()
    • Added client.BatchExists()
    • Added LDT implementation
    • Added Node and Key references to the Record

  • Changes:

    • Many minor and major bug fixes

    • Potentially breaking change: Reduced Undocumented API surface

    • Fixed a few places where error results were not checked

    • Breaking Change: Convert Key.namespace & Key.setName from pointer to string; affects Key API

    • Renamed all this receivers to appropriate names

    • Major performance improvements (~2X improvements in speed and memory consumption):

      • better memory management for commands; won't allocate if capacity is big enough
      • better hash management in key; avoids two redundant memory allocs
      • use a buffer pool to reduce GC load
      • fine-grained, customizable and deterministic buffer pool implementation for command

    • Optimizations for Key & Digest

      • changed digest implementation, removed an allocation
      • Added RIPEMD160 hash files from crypto to lib
      • pool hash objects

    • Various Benchmark tool improvements

      • now profileable using localhost:6060
      • minor bug fixes

Jul 26 2014 (Alpha)

  • Initial Release.
