Aleksey Yeschenko commented on CASSANDRA-8930:
----------------------------------------------

1. we've decided to not deprecate {{UNLOGGED}} batches just yet (see Jake's 
comment in CASSANDRA-9283), so {{BatchStatement}} must remove that client 
warning. Following that, the tests should be rewritten to use some other 
warning (a batch size based one, or TO-based one).
2. Truncation logic hasn't been updated for multiple warnings/{{string list}} 
format

I've attached a v3 with those addressed. Will commit if you are fine with the 
(minor) changes in there (you being Carl).

> Currently, if a query generates a warning, it is going to be logged server 
> side. If the person writing the query is not the admin, that warning isn't 
> going to have an impact on the query, and we're just going to fill up the 
> server logs.
> We should push these warnings back to the client so the driver users can make 
> necessary changes.
