> CASSANDRA-4914 introduces aggregate functions.
> This ticket is about to decide how we can support "user defined aggregate functions". UD aggregate functions should be supported for all UDF flavors (class, java, jsr223).
> Things to consider:
> * Special implementations for each scripting language should be omitted
> * No exposure of internal APIs (e.g. {{AggregateFunction}} interface)
> * No need for users to deal with serializers / codecs
