Depends on the underlying engine in use. If you're using RocksDB, you
will likely find what you're looking for on their wiki -
https://github.com/facebook/rocksdb/wiki
In particular, the sections - 'Write Ahead Log', 'Write Buffer Manager',
'Compaction' and 'SST File Formats'.
Finally, I'm not sure but I think questions on deep internals of the
RocksDB engine are best answered in its specific forums, where its core
maintainers are most likely to lurk.
