They also are no longer needed once they have been processed by all peer zones.

Description Matt Benjamin (redhat) 2017-08-18 02:23:22 UTC

Multisite sync is based on logs of data and metadata changes, which will continue to grow over time. Log entries should be trimmed periodically once it can be proved that no other zone will need to read them.

Data Log and Metadata Log Trimming are both implemented in RHCS 3.0.  Bucket Index Trimming and Bucket Delete cleanup now being implemented, regargeting for 3.1.

Comment 2 Matt Benjamin (redhat) 2018-05-01 11:56:17 UTC

bucket index trimming is complete in rhcs 3.1 upstream baseline, splitting out bucket delete cleanup targeting 4.0
