> 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.
