   > @davidradl Thanks for the work. I think the 
`testSelectStatementWithWeirdCharacters` you added is an orthogonal problem 
with current one, it fails without current changes, right? If yes, it can be 
another separate issue which does not block current one.

   > Current issue is mainly about how to let JDBC lookup function handle the 
pushed predicates, previously it just ignored them. So one test case I would 
like to see is one ITCase test, which shows that the result is correct with 
predicates pushed down.
   
   @libenchao Yes the join key with weird colon characters failed before. We 
are now adding filters that use the same mechanism and will not work with 
colons. The index approach works with all characters. 
   
   Based on this , I will put this code without the weird character unit test 
into this pr with the extra unit test that you suggest. I will raise a separate 
issue for the colon characters issue. @snuyanzin any concerns?
