---------------------------------
Summary: Enable Top-down Optimization
Key: CALCITE-4052
URL: https://issues.apache.org/jira/browse/CALCITE-4052
Project: Calcite
Issue Type: Task
Reporter: Rui Wang
We can enable top-down opt globally by updating saffron.properties.
Some tests will fail because top-down opt changes the output plan.
The easiest way is to update those tests to make them match the output plan
produced after top-down opt.
Alternatively, we might change testing framework to verify two output plans:
one for top-down opt, another for when top-down opt not enabled.
