> URL: https://issues.apache.org/jira/browse/IMPALA-9369
> Project: IMPALA
> Issue Type: Improvement
> Components: Catalog
> Reporter: Vihang Karajgaonkar
> Assignee: Anurag Mantripragada
> Priority: Critical
>
> In case where large number files are being inserted into a table, the
> {{createInsertEvents}} method fires insert events to HMS for each partition
> one take a time. This could be very slow for a insert statement which is
> added hundreds or thousands of files.
> We should see if we can fire the insert events asynchronously instead of
> blocking the query from returning to the user until all the insert events are
> fired.
