Hi
Just wondering what the reasons would be for keeping any snapshots older
than the most current one around? I guess one reason would be if one wanted
to restore from a certain point in time in the past with maximum
performance. Personally I don't need this, so only interested in keeping
the latest snapshot, would this be a reasonable way to do it:
case SaveSnapshotSuccess(metadata) =>
log.debug("successfully saved snapshot {}, deleting prior
snapshots...", metadata)
deleteSnapshots(SnapshotSelectionCriteria.create(metadata.sequenceNr,
metadata.timestamp - 1))
As an aside, in ShardCoordinator (2.3.5), I've noticed the snapshotTask
isn't getting cancelled in postStop(), is there a reason for that or was it
an accidental omission?
Thanks!
Peter
