> Key: PHOENIX-6952
> URL: https://issues.apache.org/jira/browse/PHOENIX-6952
> Project: Phoenix
> Issue Type: Bug
> Components: core
> Affects Versions: 5.2.0, 5.1.3
> Reporter: Istvan Toth
> Assignee: Istvan Toth
> Priority: Blocker
>
> We have taken great lengths to disable the normalizer on salte tables to
> avoid PHOENIX-4096.
> While disabling the normalizer helps with that, it also disables automatic
> splitting, which can lead to regions growing uncontrollably, and causing all
> kind of failures and data loss.
> A better solution would be disabling merges on such tables instead. The
> normalizer does check that flag. It would also restrict manual merging, but
> that can be worked around by toggling the flag manually, and is a lesser
> problem than regions growin uncontrollably.
> Alternatively, if we can fix PHOENIX-6910, then we can remove the normalizer
> restrictions.
