-------------------------------------
Summary: Skip CodeGen if expression is too large
Key: IMPALA-13289
URL: https://issues.apache.org/jira/browse/IMPALA-13289
Project: IMPALA
Issue Type: Improvement
Components: Backend
Affects Versions: Impala 4.4.0
Reporter: Riza Suminto
Running TestExprLimits::test_under_statement_expression_limit with codegen
enabled reveals big memory consumption and long codegen compilation time due to
very large expression size. Ideally, backend should recognize such case and
skip codegen to speed up query and cut memory consumption.
