In https://github.com/apache/ozone/pull/8141 RDBStore#compactTable was introduced. 

We should set options.setMaxCompactionBytes() when we open the snapshot rocksdb this could be useful so that we ensure one sub compaction doesn't take up a lot of memory. Also look into making ManagedCompactRangeOptions.setMaxSubCompactions() configurable so that we don't use a lot of CPU for this operation. It is ok if the compactions take time.

 

This can be achieved by adding ManagedRangeCompactionOption into RDBStore and its builder
