Kurt Young updated FLINK-14789: ------------------------------- Component/s: (was: Table SQL / Planner) Table SQL / API > extends max/min type in ColumnStats from Number to Comparable > ------------------------------------------------------------- > > Key: FLINK-14789 > URL: https://issues.apache.org/jira/browse/FLINK-14789 > Project: Flink > Issue Type: Sub-task > Components: Table SQL / API > Reporter: godfrey he > Assignee: godfrey he > Priority: Major > Labels: pull-request-available > Fix For: 1.10.0 > > Time Spent: 20m > Remaining Estimate: 0h > > Many tpc-ds queries have predicates on date, like {{d_date between > '1999-02-01' and (cast('1999-02-01' as date) + INTERVAL '60' day)}}, It's > very useful to find a better plan if the planner knows the max/min values of > date. However, max/min in {{ColumnStats}} only support {{Number}} type > currently. This issue aims to extend max/min type from {{Number}} to > {{Comparable}}, and then {{Date}}, {{Time}}, {{Timestamp}} even {{String}} > could be supported. -- This message was sent by Atlassian Jira (v8.3.4#803005)
