> {{hive.strict.checks.large.query}} controls the strict checks for restricting order bys with no limits, and scans of a partitioned table without a filter on the partition table.
> While both checks prevent "large" queries from being run, they both control very different behavior. It would be better if users could control these restrictions separately.
> Furthermore, many users make the mistake of abusing partitioned tables and often end up in a situation where they are running queries that are doing full-table scans of partitioned tables. This can lead to lots of issues for Hive - e.g. OOM issues because so many partitions are loaded in memory. So it would be good if we enabled this restriction by default.
