Levi Tamasi 279c488395 Mark blob files not needed by any memtables/SSTs obsolete (#6032) ... Summary: The patch adds logic to mark no longer needed blob files obsolete upon database open and whenever a flush or compaction completes. Unneeded blob files are detected by iterating through live immutable non-TTL blob files starting from the lowest-numbered one, and stopping when a blob file used by any SSTs or potentially used by memtables is found. (The latter is determined by comparing the sequence number at which the blob file became immutable with the largest sequence number received in flush notifications.) In addition, the patch cleans up the logic around closing and obsoleting blob files and enforces invariants around this area (blob files are now guaranteed to go through the stages mutable-non-obsolete, immutable-non-obsolete, and immutable-obsolete in this order). Pull Request resolved: https://github.com/facebook/rocksdb/pull/6032 Test Plan: Extended unit tests and tested using the BlobDB mode of `db_bench`.
