Radim Kolar commented on CASSANDRA-3497:
----------------------------------------
It will be good to have ability to shrink bloom filter during loading. Save
only standard cassandra bloom filters but shrink them during load according to
CF settings.
> BloomFilter FP ratio should be configurable or size-restricted some other way

> URL: https://issues.apache.org/jira/browse/CASSANDRA-3497
> Project: Cassandra
> Issue Type: New Feature
> Components: Core
> Reporter: Brandon Williams
> Priority: Minor
>
> When you have a live dc and purely analytical dc, in many situations you can
> have less nodes on the analytical side, but end up getting restricted by
> having the BloomFilters in-memory, even though you have absolutely no use for
> them. It would be nice if you could reduce this memory requirement by tuning
> the desired FP ratio, or even just disabling them altogether.
