Bridget Bevens updated DRILL-6381: ---------------------------------- Labels: doc-complete ready-to-commit (was: doc-impacting ready-to-commit) > Add capability to do index based planning and execution > ------------------------------------------------------- > > Key: DRILL-6381 > URL: https://issues.apache.org/jira/browse/DRILL-6381 > Project: Apache Drill > Issue Type: New Feature > Components: Execution - Relational Operators, Query Planning & > Optimization > Reporter: Aman Sinha > Assignee: Aman Sinha > Priority: Major > Labels: doc-complete, ready-to-commit > Fix For: 1.15.0 > > > If the underlying data source supports indexes (primary and secondary > indexes), Drill should leverage those during planning and execution in order > to improve query performance. > On the planning side, Drill planner should be enhanced to provide an > abstraction layer which express the index metadata and statistics. Further, > a cost-based index selection is needed to decide which index(es) are > suitable. > On the execution side, appropriate operator enhancements would be needed to > handle different categories of indexes such as covering, non-covering > indexes, taking into consideration the index data may not be co-located with > the primary table, i.e a global index. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
