Tamas Mate created IMPALA-10492: ----------------------------------- Summary: Lower default MAX_CNF_EXPRS query option Key: IMPALA-10492 URL: https://issues.apache.org/jira/browse/IMPALA-10492 Project: IMPALA Issue Type: Improvement Components: Backend, Frontend Affects Versions: Impala 4.0 Reporter: Tamas Mate
Currently MAX_CNF_EXPRS is set to unlimited by default, with complex queries the CNF rewrite can lead to significant frontend memory usage and eventually OutOfMemory. A potential default value could be in the range of 1000. cc.: [~amansinha], [~drorke] -- This message was sent by Atlassian Jira (v8.3.4#803005)
