Radim Kolar commented on CASSANDRA-3497:
----------------------------------------
BF configuration needs to be per CF like in HBASE. This will allow to have CF
used for log with minimal BF if their rows are rarely read back.
See HBASE for example:
http://hbase.apache.org/book/blooms.html#d1161e4353
> 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.
