--------------------------------------
Summary: Enable RocksDB auto compaction upon deletion threshold
Key: HDDS-12254
URL: https://issues.apache.org/jira/browse/HDDS-12254
Project: Apache Ozone
Issue Type: Improvement
Reporter: Wei-Chiu Chuang
RocksDB v8.11.3 and above supports a new feature
([https://github.com/facebook/rocksdb/commit/f7486ff6a31884ffd61644fb21a7ceafd7e107d1])
/
[https://github.com/facebook/rocksdb/wiki/RocksDB-Tuning-Guide#trigger-compaction-on-deletes]
(CompactOnDeletionCollectorFactory) to trigger compaction when the number of
deletion tombstones exceeds a threshold in sst files. It will require a RocksDB
upgrade because the current version is 7.7.3. However, it may not help with the
tombstones in memtable.
