# Proposed changes Issue Number: close https://github.com/apache/doris/issues/18036 ## Problem summary **Big depth of expression tree make BE stack overflow.** In pr(https://github.com/apache/doris/pull/17314) we already try to limit the depth of expression tree. Unfortunately pr(https://github.com/apache/doris/pull/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_threshold` to a large value before reproduce like issure (https://github.com/apache/doris/issues/18036) ## Checklist(Required) * [ ] Does it affect the original behavior * [ ] Has unit tests been added * [ ] Has document been added or modified * [ ] Does it need to update dependencies * [ ] Is this PR support rollback (If NO, please explain WHY) ## Further comments If this is a relatively large or complex change, kick off the discussion at [d...@doris.apache.org](mailto:d...@doris.apache.org) by explaining why you chose the solution you did and what alternatives you considered, etc... -- This is an automated message from the Apache Git Service.
