> 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
> Labels: cache, distributed, feature, new, put
> Fix For: 0.4.0
>
>
> 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.
