Sylvain Lebresne commented on CASSANDRA-7395:
---------------------------------------------
bq. I can comment out the changes in 7395 and mark them with a // TODO
CASSANDRA-7708 protocolV4 if that's ok
Can't you just remove them? The point of making a separate ticket is that we'll
deal with that later. No point in having tons of comment that makes the patch
bigger and may or may not be useful later.
As a side note, for reasonably large patch (and >100K is definitively large),
it would be really nice to try to split work in digestible commits, and ideally
to put them in some git branch somewhere. Makes reviewing (and iteration over
the review) a lot easier.

> 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.
