[jira] [Commented] (PHOENIX-3681) Store local indexes in a column family per index

["Sergey Soldatov (JIRA)" <ji...@apache.org>]

Sergey Soldatov commented on PHOENIX-3681:
------------------------------------------

Sounds like a great idea. Definitely maintenance is quite painful at the moment (dropping one of the local indexes on large table takes ages).

> 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.
