Summary: The patch builds on `BlobGarbageMeter` and `BlobCountingIterator` (introduced in https://github.com/facebook/rocksdb/issues/8426 and https://github.com/facebook/rocksdb/issues/8443 respectively) and ties it all together. It measures the amount of garbage generated by a compaction and logs the corresponding `BlobFileGarbage` records as part of the compaction job's `VersionEdit`. Note: in order to have accurate results, `kRemoveAndSkipUntil` for compaction filters is implemented using iteration. Pull Request resolved: https://github.com/facebook/rocksdb/pull/8450 Test Plan: Ran `make check` and the crash test script.

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.
Start with example usage here: https://github.com/facebook/rocksdb/tree/master/examples
See the github wiki for more explanation.
The public interface is in include/

internal APIs may be changed without warning.
Design discussions are conducted in https://www.facebook.com/groups/rocksdb.dev/ and https://rocksdb.slack.com/
