> Key: IMPALA-7469
> URL: https://issues.apache.org/jira/browse/IMPALA-7469
> Project: IMPALA
> Issue Type: Sub-task
> Reporter: Todd Lipcon
> Assignee: Todd Lipcon
> Priority: Major
> Fix For: Impala 3.1.0
>
>
> When another impalad modifies the state of a catalog object in the
> statestore, it needs to propagate that invalidation to impalads that might
> have cached some information about that object. We'll use the catalog
> statestore topic to do this propagation so that existing code paths around
> SYNC_DDL can still be supported.
