Subject [jira] [Created] (CASSANDRA-7395) Support for pure user-defined functions (UDF)
Date Thu, 12 Jun 2014 19:51:01 GMT
Jonathan Ellis created CASSANDRA-7395:

             Summary: Support for pure user-defined functions (UDF)
                 Key: CASSANDRA-7395
             Project: Cassandra
          Issue Type: New Feature
          Components: API, Core
            Reporter: Jonathan Ellis
             Fix For: 3.0

We have some tickets for various aspects of UDF (CASSANDRA-4914, CASSANDRA-5970, CASSANDRA-4998)
but they all suffer from various degrees of ocean-boiling.

Let's start with something simple: allowing pure user-defined functions in the SELECT clause
of a CQL query.  That's it.

By "pure" I mean, must depend only on the input parameters.  No side effects.  No exposure
to C* internals.  Column values in, result out.
