Turn on by default)
Key: HIVE-17164
URL: https://issues.apache.org/jira/browse/HIVE-17164
Project: Hive
Issue Type: Bug
Components: Hive
Reporter: Matt McCline
Assignee: Matt McCline
Priority: Critical
Add disk storage backing. Turn hive.vectorized.execution.ptf.enabled on by
default.
Add hive.vectorized.ptf.max.memory.buffering.batch.count to specify the maximum
number of vectorized row batch to buffer in memory before spilling to disk.
Add hive.vectorized.testing.reducer.batch.size parameter to have the Tez
Reducer make small batches for making a lot of key group batches that cause
memory buffering and disk storage backing.
