-------------------------------------
Summary: Implement a retention / purging strategy for
OMCompletedRequestInfo ledger records
Key: HDDS-15563
URL: https://issues.apache.org/jira/browse/HDDS-15563
Project: Apache Ozone
Issue Type: New Feature
Reporter: Donal Magennis
The initial implementation had no pruning strategy so the ledger grows
unbounded. We should implement some retention strategy which is pragmatic but
not too complex. Suggested Strategy: - Soft Limit (Default 100,000): Prunes
records safely behind the active consumer's checkpoint. - Hard Limit (Default
1,000,000): Protects the OM disk by unconditionally purging records older than
1,000,000 behind the latest transaction in OM, even if the consumer is offline.
