I'm afraid you cannot have a proper tabular formatting or an expand to
multiple rows (which changes significantly the semantics)
Indeed the result of the final func is returned by CQL as a whole column
and currently there is no way to change the output formatting

Thank you Doan,
Indeed I'm using a FINALFUNC to compute the average already.
Bit more context, I'm working on bucketized data, each bucket has already
an 'event count' and an 'average' in it.
My functions look as follow:
//SFUNC
CREATE OR REPLACE FUNCTION summaryState(state map >>, name text, av
A hint to answer your Q3 is to use a final function to perform the
flattening or transformation on the result of the aggregation
The syntax of an UDA is:
CREATE [OR REPLACE] AGGREGATE [IF NOT EXISTS]
aggregateName(type1, type2, …)
SFUNC accumulatorFunction
STYPE stateType
[FINALFUNC finalFunction
Hi users!
Given my Cassandra version 3.0.x I don't have the famous GROUP BY operator
available. So looking around I turned to UDAs.
I'm aware all/most of the magic happens on the coordinator and the plan is
to keep the data volume low to avoid too much pressure.
Q1: How much is low volume. It's
