Lars Hofhansl commented on PHOENIX-3681:
----------------------------------------
I think the right thing is to make this declarable. When you create a local
index you simply specify the column family it would go into (the default could
remain multiplexing into #0). That way user have all options to set this up the
way they want.
> Store local indexes in a column family per index

> 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.
