-----------------------------
Summary: 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
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.
