--------------------------------------
Note that HIVE-9499 prevents this from being used as a general config.

> Key: HIVE-12603
> URL: https://issues.apache.org/jira/browse/HIVE-12603
> Project: Hive
> Issue Type: Bug
> Components: Metastore, Query Planning
> Affects Versions: 2.0.0
> Reporter: Lenni Kuff
>
> Strict mode is useful for blocking queries that load all partitions, but it's
> still possible to put significant load on the HMS for queries that scan a
> large number of partitions. It would be useful to add a config provide a hard
> limit to the number of partitions scanned by a query.
