--------------------------------
Summary: [Snapshot] Use RocksDB to persist compaction log
Key: HDDS-7601
URL: https://issues.apache.org/jira/browse/HDDS-7601
Project: Apache Ozone
Issue Type: Sub-task
Reporter: Siyao Meng
Assignee: Siyao Meng
1. We need to deal with potential (silent) corruption against the compaction
log. We could leverage RocksDB's built-in [per-key
checksum|https://rocksdb.org/blog/2022/07/18/per-key-value-checksum.html] to
deal with it rather than handling it ourselves.
2. Implement an {{OmDBMetaInfoManager}} interface that could use either plain
text or RocksDB as the backend storage. Or maybe just RocksDB for simplicity.
3. This means each OM would have its own metadata DB that stores information
about the main OM DB, where we could store compaction log, SST filtering status
and potentially more.
