Make index_interval configurable per column family
--------------------------------------------------
Key: CASSANDRA-3961
URL: https://issues.apache.org/jira/browse/CASSANDRA-3961
Project: Cassandra
Issue Type: Improvement
Affects Versions: 1.0.7
Environment: Cassandra 1.0.7/unix
Reporter: Radim Kolar
Priority: Minor
After various experiments with mixing OLTP a OLAP workload running on single
cassandra cluster i discovered that lot of memory is wasted on holding index
samples for CF which are rarely accessed or index is not much used for CF
access because slices over keys are used.
There is per column family setting for configuring bloom filters -
bloom_filter_fp_chance. Please add setting index_interval configurable per CF
as well. If this setting is not set or it is zero, default from cassandra.yaml
will be used.
