James Taylor commented on PHOENIX-2885:
---------------------------------------
We could get fancy to handle detection of dropped entities (columns, views,
sequences, etc.) through some kind of zk trickery, but not sure if it's worth
it - we can file a separate JIRA for that. Often destructive deletions are
disallowed in production systems anyway.

> Key: PHOENIX-2885

> Project: Phoenix
> Issue Type: Bug
> Reporter: James Taylor
> Fix For: 4.9.0
>
>
> With the increased usage of the UPDATE_CACHE_FREQUENCY property to reduce
> RPCs, we increase the chance that a separate client attempts to access a
> column that doesn't exist on the cached entity. Instead of throwing in this
> case, we can update the client-side cache. This works well for references to
> entities (columns, tables) that don't yet exist. For entities that *do*
> exist, we won't detect that they've been deleted.
