Ali Alsuliman resolved ASTERIXDB-2286. -------------------------------------- Resolution: Done > Parallel Sort Optimization > -------------------------- > > Key: ASTERIXDB-2286 > URL: https://issues.apache.org/jira/browse/ASTERIXDB-2286 > Project: Apache AsterixDB > Issue Type: Improvement > Components: COMP - Compiler, FUN - Functions, HYR - Hyracks > Affects Versions: 0.9.4 > Reporter: Ali Alsuliman > Assignee: Ali Alsuliman > Priority: Major > Labels: triaged > Fix For: 0.9.4.2 > > > The current plan for queries with ORDER BY clauses consists of two phases; > sorting the data locally in each partition and then sort-merging the data in > one single partition. Even though the local sort happens in parallel, this > effort is wasted by the fact that the merge is happening at one partition. It > is desired to remove the merge step and do a true parallel sort where data is > range-partitioned across the cluster. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
