Michael Smith reassigned IMPALA-13027: -------------------------------------- Assignee: Jason Fehr > Directly create exec request for query log inserts > -------------------------------------------------- > > Key: IMPALA-13027 > URL: https://issues.apache.org/jira/browse/IMPALA-13027 > Project: IMPALA > Issue Type: Improvement > Reporter: Michael Smith > Assignee: Jason Fehr > Priority: Major > > Inserts into {{sys.impala_query_log}} can be large, as they include the query > profile and currently 49 columns for each query. Right now inserts are > executed via an SQL statement, which needs to be parsed by Impala's Frontend. > This can take a non-trivial amount of time - on the order of seconds - when > reaching the query queue limit (1000s of queries), and also require > increasing the {{statement_expression_limit}} above 250k. > We could improve this by directly constructing the TExecRequest for the > insert in InternalServer (likely via a new function API). This would also let > us avoid needing to escape strings in the SQL statement by directly > constructing the relevant type objects. -- 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
