Summary: Pull Request resolved: https://github.com/facebook/rocksdb/pull/15074 Why: We want to be able to monitor how many remote compaction jobs are running on a given server. Currently we know the total number of running compactions but not the local vs remote breakdown. What: Add a new `rocksdb.num-running-remote-compaction-jobs` statistic. This measures in-progress remote compaction jobs. Note that remote compaction work is scheduled per subcompaction, so one RocksDB compaction may contribute more than one running remote compaction job.

RocksDB: A Persistent Key-Value Store for Flash and RAM Storage
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 especially suitable for storing multiple terabytes of data in a single database.
