Benjamin Lerer commented on CASSANDRA-9802:
-------------------------------------------

Detecting in cqlsh that we are using aggregate is a bit of work with UDA. Why 
are we not internally using our own page size as we know when it is an 
aggregate. We could fix a lower limit (e.g. 10 000) .

> Better page size for aggregates in cqlsh

> As discussed in CASSANDRA-9724, cqlsh uses a small page size (100) which 
> makes sense for "normal" queries since you don't want to flood the terminal, 
> but is quite sub-optimal for aggregates where the page size is used as the 
> internal page size for the aggregate (there is thus no terminal flooding 
> concerns and a page size of 100 is too low).
> We should thus make cqlsh use a bigger page size (stick with the python 
> driver default for instance) when dealing with aggregate queries. According 
> to Tyler:
> bq. it's not trivial, but it is possible. It should take a day or less of 
> work.
