Michael Smith resolved IMPALA-5081. ----------------------------------- Fix Version/s: Impala 4.4.0 Resolution: Fixed > Expose IR optimization level via query option > --------------------------------------------- > > Key: IMPALA-5081 > URL: https://issues.apache.org/jira/browse/IMPALA-5081 > Project: IMPALA > Issue Type: Improvement > Components: Backend > Reporter: Michael Ho > Assignee: Michael Smith > Priority: Minor > Labels: codegen > Fix For: Impala 4.4.0 > > > Certain queries may spend a lot of time in the IR optimization. Currently, > there is a start-up option to disable optimization in LLVM. However, it may > be of inconvenience to users to have to restart the entire Impala cluster to > just use that option. This JIRA aims at exploring exposing a query option for > users to choose the optimization level for a given query (e.g. we can have a > level which just only have a dead code elimination pass or no optimization at > all). -- This message was sent by Atlassian Jira (v8.20.10#820010) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-all-unsubscr...@impala.apache.org For additional commands, e-mail: issues-all-h...@impala.apache.org
