|
|
|
RocksDB is developed and maintained by Facebook Database Engineering Team.
|
|
It is built on earlier work on [LevelDB](https://github.com/google/leveldb) by Sanjay Ghemawat (sanjay@google.com)
|
|
and Jeff Dean (jeff@google.com)
|
|
|
|
This code is a library that forms the core building block for a fast
|
|
key value server, especially suited for storing data on flash drives.
|
|
It has a Log-Structured-Merge-Database (LSM) design with flexible tradeoffs
|
|
between Write-Amplification-Factor (WAF), Read-Amplification-Factor (RAF)
|
|
and Space-Amplification-Factor (SAF). It has multi-threaded compactions,
|
|
making it specially suitable for storing multiple terabytes of data in a
|
|
single database.
|
|
|
|
Start with example usage here: https://github.com/facebook/rocksdb/tree/master/examples
|
|
|
|
See the [github wiki](https://github.com/facebook/rocksdb/wiki) for more explanation.
|
|
|
|
The public interface is in `include/`. Callers should not include or
|
|
rely on the details of any other header files in this package. Those
|
|
internal APIs may be changed without warning.
