Lefty Leverenz commented on HIVE-11777:
---------------------------------------
Typo alert: "geneation" presumably should be "generation" in the patch's
description of *hive.orc.splits.strategy.batch.ms*.
Also, the description could be clearer. "0 means don't" should be "0 means
don't wait" (or maybe "0 means don't batch"). And is it just me, or is the
phrase "to batch split strategies" confusing?
> implement an option to have single ETL strategy for multiple directories

> In case of metastore footer PPD we don't want to call PPD call with all
> attendant SARG, MS and HBase overhead for each directory. If we wait for some
> time (10ms? some fraction of inputs?) we can do one call without losing
> overall perf.
> For now make it time based.
> NO PRECOMMIT TESTS
