Robert Stupp resolved CASSANDRA-7674.
-------------------------------------
Resolution: Not a Problem
bq. imo, we shouldn't do automagical stuff
Although I think that upcasting {{int}} to {{bigint}} is a nice feature, some
other casts should definetely avoided (e.g. {{long}} to {{double}}). So this
"implicit casting" could introduce more hidden problems with user code than
solve something. We can rely on that {{varint}}/{{decimal}} sub-typing.
> Add implicit casting of UDF arguments

> Key: CASSANDRA-7674
> URL: https://issues.apache.org/jira/browse/CASSANDRA-7674
> Project: Cassandra
> Issue Type: Improvement
> Reporter: Robert Stupp
>
> Writing implementations for each possible combination of even most
> "primitive" CQL types is waste of time and results in unclear code.
> E.g. a {{divide}} function should accept {{int, bigint, float, double}} for
> the first and second paramter.
> Better if UDF implementation can automagically do some up-casting ({{int}} to
> {{bigint}}, {{float}} to {{double}} etc).
