Jonathan Ellis commented on CASSANDRA-3074:
-------------------------------------------
the proposed changes conflate the index entries themselves (always one per key)
and the sampling rate (which is what index_interval affects).
> comments and documentation for index_interval are misleading

> The comments and documentation for index_interval are misleading. They state
> the larger the *sampling* the more effective the index as at the cost of
> space. This is true, but in the context of the configuration variable it
> implies the larger the *setting* is the larger the index is while in fact
> it's the opposite of that.
