> Avoid scanner caching in Phoenix
> --------------------------------
>
> Key: PHOENIX-4266
> URL: https://issues.apache.org/jira/browse/PHOENIX-4266
> Project: Phoenix
> Issue Type: Bug
> Reporter: Lars Hofhansl
> Priority: Major
> Fix For: 5.1.0, 4.16.1, 4.17.0
>
>
> Phoenix tries to set caching on all scans. On HBase versions before 0.98 that
> made sense, now it is the wrong thing to do.
> HBase will by default do size based chunking. Setting scanner caching
> prevents HBase doing this work.
> We should avoid scanner everywhere, and only use in cases where we know the
> number of rows to be returned (and that number is small).
