----------------------------------------

[~rajeshbabu] I somehow missed your comment above. I think your idea in PHOENIX-3566 is the right way to go about it. Are you still thinking about this?

>            Priority: Major

> Currently all local indexes are stored in a single column family. That makes maintenance (such as dropping an index) more expensive than necessary.
> Let's have each local index in its own column family (or be able to declare which column family an index should go into).
> As [~jamestaylor] points out, this won't work for indexes on views as there might be 1000's of them.
> Another issue are covered local indexes, but I'd argue that local indexes would benefit little from being covered. (that also needs to be experimentally verified)
> Local indexes in individual column families would be great to isolate any maintenance and even usage from each other.
