> Key: HDDS-15563
> URL: https://issues.apache.org/jira/browse/HDDS-15563
> Project: Apache Ozone
> Issue Type: New Feature
> Reporter: Donal Magennis
> Priority: Major
> Labels: EventNotification, pull-request-available
>
> 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.
