------------------------------------
Summary: Enable result spooling by default
Key: IMPALA-9856
URL: https://issues.apache.org/jira/browse/IMPALA-9856
Project: IMPALA
Issue Type: Task
Components: Backend
Reporter: Sahil Takiar
Result spooling has been relatively stable since it was introduced, and it has
several benefits described in IMPALA-8656. It would be good to enable it by
default.
I looked into doing this a while ago, and there are a bunch of tests that rely
on the "fetch one row batch at a time" behavior. Those tests fail when result
spooling is enabled.
The remaining linked tasks in IMPALA-8656 should be completed as well before
enabling result spooling by default.
