go-ycsb

go-ycsb is a Go port of YCSB. It fully supports all YCSB generators and the Core workload so we can do the basic CRUD benchmarks with Go.

Why another Go YCSB?

  • We want to build a standard benchmark tool in Go.
  • We are not familiar with Java.

Getting Started

git clone https://github.com/pingcap/go-ycsb.git $GOPATH/src/github.com/pingcap/go-ycsb
cd $GOPATH/src/github.com/pingcap/go-ycsb
make

./bin/go-ycsb

Notice:

  • To use FoundationDB, you must install client library at first, now the supported version is 6.0.15.
  • To use RocksDB, you must follow INSTALL to install RocksDB at first.

Usage

Mostly, we can start from the offical document Running-a-Workload.

Shell

./bin/go-ycsb shell basic
» help
YCSB shell command

Usage:
  shell [command]

Available Commands:
  delete      Delete a record
  help        Help about any command
  insert      Insert a record
  read        Read a record
  scan        Scan starting at key
  table       Get or [set] the name of the table
  update      Update a record

Load

./bin/go-ycsb load basic -P workloads/workloada

Run

./bin/go-ycsb run basic -P workloads/workloada

rocksdb.max_bytes_for_level_multiplier 10 Sets the max Bytes for level multiplier
rocksdb.max_total_wal_size 0([sum of all write_buffer_size * max_write_buffer_number] * 4) Sets the maximum total wal size in bytes. Once write-ahead logs exceed this size, we will start forcing the flush of column families whose memtables are backed by the oldest live WAL file (i.e. the ones that are causing all the space amplification)
rocksdb.memtable_huge_page_size 0 Sets the page size for huge page for arena used by the memtable

rocksdb.block_size_deviation 10 Sets the block size deviation. This is used opts close a block before it reaches the configured 'block_size'. If the percentage of free space in the current block is less than this specified number and adding a new record opts the block will exceed the configured block size, then this block will be closed and the new record will be written opts the next block
rocksdb.cache_index_and_filter_blocks false Indicating if we'd put index/filter blocks to the block cache. If not specified, each "table reader" object will pre-load index/filter block during table initialization
rocksdb.no_block_cache false Specify whether block cache should be used or not
rocksdb.pin_l0_filter_and_index_blocks_in_cache false Sets cache_index_and_filter_blocks. If is true and the below is true (hash_index_allow_collision), then filter and index blocks are stored in the cache, but a reference is held in the "table reader" object so the blocks are pinned and only evicted from cache when the table reader is freed
rocksdb.whole_key_filtering true Specify if whole keys in the filter (not just prefixes) should be placed. This must generally be true for gets opts be efficient
rocksdb.block_restart_interval 16 Sets the number of keys between restart points for delta encoding of keys. This parameter can be changed dynamically
rocksdb.filter_policy nil Sets the filter policy opts reduce disk reads. Many applications will benefit from passing the result of NewBloomFilterPolicy() here
