Description

One test is breaking in the 4.0.0 RC2, hence I marked this as blocker. liuyao , I picked your name as the assignee since I thought you might be knowledgeable about this part of the codebase. Here's the test output:

E   assert Items in expected results not found in actual results:
E     '     partitions: 0/24 rows=17.91K'
E     Items in actual results:
