Timo Walther created FLINK-7271: ----------------------------------- Summary: ExpressionReducer does not optimize string-to-time conversion Key: FLINK-7271 URL: https://issues.apache.org/jira/browse/FLINK-7271 Project: Flink Issue Type: Improvement Components: Table API & SQL Reporter: Timo Walther
Expressions like {{"1996-11-10".toDate}} or {{"1996-11-10 12:12:12".toTimestamp}} are not recognized by the ExpressionReducer and are evaluated during runtime instead of pre-flight phase. In order to optimize the runtime we should allow constant expression reduction here. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
