I'm actively working this, I pushed my branch up in case anyone wants to take a look [1]. The idea is to abstract the Cassandra API "up a couple levels" and provide implementations for Cassandra 3, 4, and eventually 5. For JDBC-like interfaces this is a PITA because of the API (Statement, PreparedStatement, BoundStatement, ResultSet, etc.) but I'm hoping we can find a common pattern for abstracting the third-party library implementation and API from the NiFi component (Processor, ControllerService, etc.) API. I think we're doing something similar for Kafka?
