----------------------------------------
Summary: Add functions to return TimeIndicators from
MATCH_RECOGNIZE
Key: FLINK-10591
URL: https://issues.apache.org/jira/browse/FLINK-10591
Project: Flink
Issue Type: Sub-task
Components: CEP, Table API & SQL
Affects Versions: 1.7.0
Reporter: Dawid Wysakowicz
In order to be able to apply windowing on top of results from MATCH_RECOGNIZE
clause we have to provide a way to return proper TimeIndicator. We cannot
simply return rowtime/proctime for any row of the match, cause match can be
finalized e.g. by the first non matching row (in case of greedy), so the
TimeIndicator will be equal to the timestamp of that non-matching row.
The suggestion is to provide functions:
* MATCH_ROWTIME()
* MATCH_PROCTIME()
that will output rowtime/proctime indicators.
