Sylvain Lebresne commented on CASSANDRA-7395: --------------------------------------------- bq. it's in fact as simple as this to create an object from a class that's just been compiled. That's the "that's just been compiled" that bothers me. If we're talking about writing a text file and call javac on it as an external program, then I *definitively* prefer moving that as as step 2. > Support for pure user-defined functions (UDF) > --------------------------------------------- > > Key: CASSANDRA-7395 > URL: https://issues.apache.org/jira/browse/CASSANDRA-7395 > Project: Cassandra > Issue Type: New Feature > Components: API, Core > Reporter: Jonathan Ellis > Labels: cql > Fix For: 3.0 > > Attachments: 7395-v2.diff, 7395.diff > > > 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.
