Brandon Williams commented on CASSANDRA-3264:
---------------------------------------------

bq. To clarify: I'm saying CFIF should allow specifying a CQL query, alongside 
the existing SlicePredicate API. Then we solve this problem for "free" when 
CASSANDRA-2474 is done.

+1 to that, then, I only suggested not waiting for CASSANDRA-2474 when this was 
seemingly more urgent than it is now.

> Hadoop input/output formats currently can OOM on wide rows.
> We can add a new option to the ConfigHelper like columnPagingSize with a 
> default of Integer.MAX_VALUE.
> The input format would page the row internally rather than pull it over at 
> once.
> The output format could also use this to avoid sending huge rows over at once.
