Summary: Both the single deletion and the value are included in compaction outputs, so no need to update the stat for the value's deletion yet, otherwise it'd be double-counted.

## RocksDB: A Persistent Key-Value Store for Flash and RAM Storage
[](https://travis-ci.org/facebook/rocksdb)
[](https://ci.appveyor.com/project/Facebook/rocksdb/branch/master)
RocksDB is developed and maintained by Facebook Database Engineering Team.
It is built on earlier work on 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.
