Matt McCline created HIVE-17164: ----------------------------------- Summary: Vectorization: Support PTF (Part 2: Unbounded Support-- 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. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
