Rui Li commented on FLINK-21637:
--------------------------------
The logical plan is:
{noformat}
== Abstract Syntax Tree ==
LogicalProject(s=[$0])
+- LogicalFilter(condition=[=(2021-03-05 20:35:01, CAST($1):TIMESTAMP(0))])
+- LogicalTableScan(table=[[default_catalog, default_database, src, source:
[CollectionTableSource(s, ts)]]])
{noformat}
So calcite casts the {{ts}} column to TIMESTAMP(0), which I think is wrong.
