> 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}}.
