Timo Walther created FLINK-6547:
-----------------------------------
Summary: Improve toString methods of Table API expressions
Key: FLINK-6547
URL: https://issues.apache.org/jira/browse/FLINK-6547
Project: Flink
Issue Type: Improvement
Components: Table API & SQL
Reporter: Timo Walther
Right now, we logically test windows like this:
{code}
term(
"window",
TumblingGroupWindow(
WindowReference("w1"),
'proctime,
50.milli)),
{code}
But this does not test if the proctime attribute is resolved nor checks the
time indicator type.
If we still rely on string comparison for tests, we need to make sure that all
expressions have a rich {{toString}} function with sufficient information.
