Subject [jira] [Commented] (PHOENIX-3681) Store local indexes in a column family per index
Date Wed, 26 Apr 2017 23:46:04 GMT

    [ https://issues.apache.org/jira/browse/PHOENIX-3681?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15985762#comment-15985762

Lars Hofhansl commented on PHOENIX-3681:
----------------------------------------

Any more comments:
The syntax could just something like {{CREATE LOCAL INDEX ON mytable(mycolumn, ...) STORE
IN mycolumnfamily;}} (or something)

> 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.
