---------------------------------
Summary: Expose per column family compaction metrics for RocksDB
Key: HDDS-17170
URL: https://issues.apache.org/jira/browse/HDDS-17170
Project: Apache Ozone
Issue Type: Improvement
Components: metrics, db
Reporter: Siyao Meng
RocksDBStoreMetrics already exposes some properties per column family (e.g.
live-sst-files-size, estimate-num-keys), but compaction statistics come from
the DB wide Statistics object. It is not possible to tell which table (e.g.
keyTable, deletedTable, directoryTable in OM) is driving compaction load.
Expose per column family compaction metrics, e.g. from the rocksdb.cfstats map
property: compaction count, time, bytes read and written.
