Unfortunately templates exported from NiFi do not contain Controller
Services that are not referenced by one of the selected extensions.
As a result, yes, this would be another Controller Services entry.
Something to the effect of the following should work:
- id: <unique id>
name: Map Cacher Server
type: org.apache.nifi.distributed.cache.server.map.DistributedMapCacheServer
Properties:
Port: 4557
Maximum Cache Entries: 10000
Eviction Strategy: "Least Frequently Used"
These properties are derived from:
https://github.com/apache/nifi/blob/master/nifi-nar-bundles/nifi-standard-services/nifi-distributed-cache-services-bundle/nifi-distributed-cache-server/src/main/java/org/apache/nifi/distributed/cache/server/DistributedCacheServer.java
Admittedly, this is not necessarily a target case but is certainly
doable. The caveat is that our tooling is a bit light at the moment
to support such scenarios but we certainly hope to make such processes
easier in the future.
Let us know if you experience any additional issues.
