Subject [jira] [Created] (CASSANDRA-5047) Allow bloom_filter_fp_chance to be configured differently per data center
Date Sun, 09 Dec 2012 23:53:21 GMT
Delaney Manders created CASSANDRA-5047:
------------------------------------------

             Summary: Allow bloom_filter_fp_chance to be configured differently per data center
                 Key: CASSANDRA-5047
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-5047
             Project: Cassandra
          Issue Type: New Feature
          Components: Core
    Affects Versions: 1.2.0 rc1
            Reporter: Delaney Manders
            Priority: Minor


When using one data center for hadoop/analytics exclusively, one for serving high volume writes,
and possibly even one for reads, the tuning requirements are dramatically different on the
same column family.

The biggest heap cost on a large dataset is the bloom_filter.  It would be great to be able
to disable/tune it as a per-datacentre setting.
