> Key: GEODE-10391
> URL: https://issues.apache.org/jira/browse/GEODE-10391
> Project: Geode
> Issue Type: Bug
> Components: regions
> Affects Versions: 1.16.0
> Reporter: Bill Burcham
> Assignee: Bill Burcham
> Priority: Major
> Labels: pull-request-available
>
> When a primary moves while a region operation, e.g. create, is in-flight,
> i.e. started but not yet acknowledged, the operation will be retried
> automatically, until the operation succeeds or fails.
> When a member notices another member has crashed, the surviving member
> requests (from the remaining members) data for which the crashed member had
> been primary (delta-GII/sync). This sync is necessary to regain consistency
> in case the (retrying) requester fails before it can re-issue the request to
> the new primary.
> In GEODE-5055 we learned that we needed to delay that sync request long
> enough for the new primary to be chosen and for the original requester to
> make a new request against the new primary. If we didn't delay the sync, the
> primary could end up with the entry in the new state (as if the operation had
> completed) but without the corresponding event tracker data needed to
> conflate the retried event.
> The fix for GEODE-5055 introduced a delay, but only for configurations where
> clients were present. If only peers were present there would be no delay.
> This ticket pertains to the P2P-only case.
