Lyuben Todorov commented on CASSANDRA-6066:
-------------------------------------------

bq. We should perform more aggressive paging over the index partition
[~iamaleksey] Can you elaborate a bit?  

As for fetching the rows from the base cf (and it's tables), as far as i can see a good starting point would be to try to work out if the list of {{SecondaryIndexSearcher}}s can be narrowed down to a single search (im talking about SecondaryIndexManager#search}}).

> We should perform more aggressive paging over the index partition (costs us nothing) and also fetch the rows from the base table in one slice query (at least the ones belonging to the same partition).
