[jira] [Created] (NIFI-8919) Refactor Distributed Cache Clients using Netty

David Handermann created NIFI-8919:
--------------------------------------

             Summary: Refactor Distributed Cache Clients using Netty
                 Key: NIFI-8919
                 URL: https://issues.apache.org/jira/browse/NIFI-8919
             Project: Apache NiFi
          Issue Type: Improvement
          Components: Extensions
    Affects Versions: 1.15.0
            Reporter: David Handermann


The {{DistributedMapCacheClientService}} and {{DistributedSetCacheClientService}} leverage {{SSLSocketChannel}} through {{SSLCommsSession}} to support TLS communication, which involves custom interaction with {{javax.net.ssl.SSLEngine}}. Refactoring these client services using Netty would remove the need for custom {{SSLEngine}} interaction and also streamline the protocol implementation. Changes will involve replacement of the existing {{CommsSession}} interface with higher-level client and custom Netty Handlers implementation the distributed cache protocol.
