Subject [jira] [Commented] (PHOENIX-5096) Local index region pruning is not working as expected.
Date Thu, 10 Jan 2019 23:54:00 GMT


Lars Hofhansl commented on PHOENIX-5096:

I'll stop now and wait for comments. :)

The gist of what I am saying it this:
# Region pruning should be generally done (and is possible), even when we're not adding the
local index key.
# The local index should be as usable as before (i.e. use and ping every region).

> Local index region pruning is not working as expected.

>          Issue Type: Bug
>            Reporter: Lars Hofhansl
>            Priority: Major
> The pruning of local indexes should do the following:
> * Use the local index
> * Reduce the number of regions based on filters on the table's primary key (i.e. WHERE
conditions including prefixes of the primary key)
> Instead it looks like in order for this to work the needed PK column need to be included
in the local index itself, changing the sort order of the local index.
> I'll provide some examples in the comments.
