Can we add some test overages to it ?

[chenjian2664]

Thanks @Praveen2112, I am adding 👍

@Praveen2112 Could you suggest where and how could to test for this part?
There is a test class TestPushJoinIntoTableScan but feel like not suitable to add test here, actually we need test is sth like "Test merge plan's right join, left scan table is a target". Any thoughts?
