-----------------------------------
Summary: Add LocalMapCacheService
Key: NIFI-3488
URL: https://issues.apache.org/jira/browse/NIFI-3488
Project: Apache NiFi
Issue Type: Improvement
Components: Extensions
Reporter: Koji Kawamura
Currently we have DistributedMapCacheClientService to share values among
different processors across NiFi nodes. However it can be an extravagance if
users would like to use the cache only for sharing values locally within a node
instead of cluster wide.
LocalMapCacheService can be useful in that cases, provides benefits such as,
being able to use existing Processors those use DistributedMapCacheClient, no
need to transfer data over network, don't have to worry about cache key
collision ... etc.
The implementation can be as simple as having a Map on heap. Optionally persist
MapEntries to local filesystem.
