Zhenhua Wang created SPARK-32786:
------------------------------------
Summary: Improve performance for some slow DPP tests
Key: SPARK-32786
URL: https://issues.apache.org/jira/browse/SPARK-32786
Project: Spark
Issue Type: Improvement
Components: SQL
Affects Versions: 3.1.0
Reporter: Zhenhua Wang
The whole `DynamicPartitionPruningSuite` takes about 2 min in my laptop (either
AE on or off). The slowest tests are `test("simple inner join triggers DPP with
mock-up tables")` and `test("cleanup any DPP filter that isn't pushed down due
to expression id clashes")`, which totally takes about 1 min.
We can reuse existing test tables or use smaller tables to reduce the cost.
After that, the two tests takes only about 1 sec in total, leading to 2x
speedup for the suite.
