Lars Hofhansl commented on PHOENIX-2885:
----------------------------------------

Not sure it's worth it.

In many case the query would compile correctly but then fail during execution 
(for example when we drop a column). In that case we can catch the failed 
execution and detect whether it was because of the missing 
column/table/view/etc and in that case update the cache and try again (but only 
once). In addition we probably want to keep the UPDATE_CACHE_FREQUENCY as an 
additional option
(in case a client repeatedly issues an incorrect query with a missing column).

> 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.
