---------------------------------
Summary: PutDistributedMapCache processor
Key: NIFI-988
URL: https://issues.apache.org/jira/browse/NIFI-988
Project: Apache NiFi
Issue Type: New Feature
Components: Core Framework
Reporter: Joe Mészáros
Priority: Minor
There is a standard controller service, called DistributedMapCacheServer, which provides a
distributed cache, and an associated DistributedMapCacheClientService to interact with the
cache. But there is not any standard processor, which puts data into the cache, and helps
the user to leverage the distributed cache capabilities.
The purpose of PutDistributedMapCache is very similar to the egress processors: it gets the
content of a FlowFile and puts it to a distributed map cache, using a cache key computed from
FlowFile attributes. If the cache already contains the entry and the cache update strategy
is 'keep original' the entry is not replaced.
