Tim Armstrong updated IMPALA-8083: ---------------------------------- Labels: performance (was: ) > Materialize sub parts of query that is used in multiple times in a query > ------------------------------------------------------------------------ > > Key: IMPALA-8083 > URL: https://issues.apache.org/jira/browse/IMPALA-8083 > Project: IMPALA > Issue Type: Improvement > Components: Backend, Frontend > Reporter: Janaki Lahorani > Priority: Major > Labels: performance > > When the same bit of processed data is used in multiple places (within the > query to begin with), it should be materialized. Some use cases are grouping > set queries where one group computation can be derived from other group > computation, with clause, data mining like queries and graph processing > queries. To begin with, the materialized data could be scoped for the query. > But this has the potential to grow to a group of queries. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-all-unsubscr...@impala.apache.org For additional commands, e-mail: issues-all-h...@impala.apache.org
