             Summary: Store local indexes in a column family per index
                 Key: PHOENIX-3681
                 URL: https://issues.apache.org/jira/browse/PHOENIX-3681
             Project: Phoenix
          Issue Type: Bug
            Reporter: Lars Hofhansl


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.
