Proposed changes
Issue Number: close #18036
Problem summary
Big depth of expression tree make BE stack overflow.
In pr(#17314) we already try to limit the depth of expression tree.
Unfortunately pr(#17314) limit the depth in prepare stage, we already stack overflow in init stage, because of recursive call of create_tree_from_thrift.
So we refractor create_tree_from_thrift use non-recursive traversal, to prevent stack overflow.
How to reproduce it in master?
We should set
rewrite_or_to_in_predicate_thresholdto a large value before reproduce like issure (#18036)Checklist(Required)
