@Kyrylo, In Rocksandra world, the storage engine is built on top of
RocksDB, which is another LSM tree based storage engine. So the immutable
sstables and compactions are managed by RocksDB instances. RocksDB supports
different compaction strategies, similar to STCS and LCS. The compactions
are managed by C++, so it will not generate any pressure to JVM.
@Romain, Thanks, and Rocksandra is not limited to only support key/value
data model. We support most of the data types and table data model in
