A Go port of Yahoo! Cloud Serving Benchmark (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.

| 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.block_restart_interval | 16 | Sets the number of keys between restart points for delta encoding of keys. This parameter can be changed dynamically |
