> I'm currently trying to speed up the {{alter table rename to}} feature of HMS. The recently
submitted change (HIVE-9447) already helps a lot especially on Oracle HMS DBs.
> This time I intend to gain throughput independently of DB types by enabling HMS to execute
this alter table command on batches of partitions (rather than 1by1)
