Summary: Within the DistributedMapCacheServer, it would be
beneficial to more easily purge the entire entry list and specific entries with
a particular Cache Entry Identifier
Key: NIFI-7217
URL: https://issues.apache.org/jira/browse/NIFI-7217
Project: Apache NiFi
Issue Type: Improvement
Reporter: Henry Sowell
Currently, I use the DetectDuplicate processor, leveraging the
DistributedMapCacheService and DistributedMapCacheServer. I have a flow where
we need to periodically reprocess data and need to purge what's stored in the
DistributedMapCacheServer. Because our DMCserver was configured to persist
cache entries to disk, we are required to manually stop the server, and delete
the cache on disk, then restart the server to purge entries. It would be
beneficial to be able to more easily purge the entire entry list and specific
entries with a specific Cache Entry Identifier. This could be accomplished in a
variety of ways (e.g., a button from the controller services menu, within
Detect Duplicate processor, etc.).
