> Dropping a set of N partitions from a table currently results in N
> DropPartitionEvents (and N PreDropPartitionEvents) being fired serially. This
> is wasteful, especially so for large N. It also makes it impossible to even
> try to run authorization-checks on all partitions in a batch.
> Taking the cue from HIVE-9609, we should compose an {{Iterable<Partition>}}
> in the event, and expose them via an {{Iterator}}.
