The goal is to provide statistics support in Drill which will help build better plans in Drill. This design borrows ideas from the earlier design. However, we try to address some concerns in the earlier design. Please review the specification and provide feedback. The link to the specification is present in the JIRA Issue Links section. Thanks, Gautam --001a114cc2a0dc27c10537ef6323--
