Make secondary indexes inherit compression (and maybe other properties) from 
their base CFS
-------------------------------------------------------------------------------------------

                 Key: CASSANDRA-3877
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-3877
             Project: Cassandra
          Issue Type: Improvement
          Components: Core
    Affects Versions: 1.0.0
            Reporter: Sylvain Lebresne
            Priority: Minor
             Fix For: 1.1


Secondary indexes currently use the defaults for most properties and only 
inherit a few properties from their base CFS (namely gc_grace and the min/max 
compaction thresholds currently). It would make sense to have them inherit more 
properties. At least compression makes sense, but the compaction parameters 
probably do too (and maybe bf_filter_chance?).

In any case, making secondary indexes inherit those probably is trivial, but I 
think we should also make it so that if the base CF is modified, we mirror the 
changes to it's secondary indexes.
