>
> Currently the PartitionPruner requests either all partitions or partitions
> based on filter expression. In either scenarios, if the number of partitions
> accessed is large there can be significant memory pressure at the HMS server
> end.
> We already have a config {{hive.limit.query.max.table.partition}} that
> enforces limits on number of partitions that may be scanned per operator. But
> this check happens after the PartitionPruner has already fetched all
> partitions.
> We should add an option at PartitionPruner level to disallow queries that
> attempt to access number of partitions beyond a configurable limit.
> Note that {{hive.mapred.mode=strict}} disallow queries without a partition
> filter in PartitionPruner, but this check accepts any query with a pruning
> condition, even if partitions fetched are large. In multi-tenant
> environments, admins could use more control w.r.t. number of partitions
> allowed based on HMS memory capacity.
> One option is to have PartitionPruner first fetch the partition names
> (instead of partition specs) and throw an exception if number of partitions
> exceeds the configured value. Otherwise, fetch the partition specs.
> Looks like the existing {{listPartitionNames}} call could be used if extended
> to take partition filter expressions like {{getPartitionsByExpr}} call does.
