-----------------------------------
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.
