Robert Stupp commented on CASSANDRA-7395:
-----------------------------------------
Unclear for me yet (maybe stuff for a followup ticket):
* does it make sense to add another system KS table 'schema_bundles'
* use that 'schema_bundles' table to distribute JAR files
* or use that 'schema_functions' table to distribute binary class files
Others:
* Use K_USING instead of K_AS (remove that) to match CREATE TRIGGER syntax
Note:
CREATE FUNCTION/BUNDLE now also support IF NOT EXISTS. So the syntax is
{{CREATE [ OR REPLACE | IF NOT EXISTS ] FUNCTION/BUNDLE}}
Syntax needs some change to move "IF NOT EXISTS" after FUNCTION/BUNDLE.
> Support for pure user-defined functions (UDF)

> 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.
