--------------------------------
> Duplicate Ops During GII/Delta Updates
> ---------------------------------------
>
> Key: GEODE-10108
> URL: https://issues.apache.org/jira/browse/GEODE-10108
> Project: Geode
> Issue Type: Bug
> Components: redis
> Reporter: Wayne
> Assignee: Jens Deppe
> Priority: Major
> Labels: blocks-1.15.0, pull-request-available
> Fix For: 1.15.0
>
>
> When Redis commands are ongoing and a server that was previously not hosting
> a bucket becomes the host of the primary bucket for a key, there exists a
> time window where that server is performing GII but also receiving delta
> updates from the previous primary bucket. This can lead to the delta being
> applied to a data structure that is already in the “correct” state, resulting
> in the command being applied twice. This can result in duplicated appends,
> increments/decrements, and in the case of LTRIP and RPOP especially,
> IndexOutOfBoundsException on the member applying the delta, as the index to
> which the delta refers has already been removed.
