Summary: Refactor handling of time indicator attributes
Key: FLINK-7337
URL: https://issues.apache.org/jira/browse/FLINK-7337
Project: Flink
Issue Type: Improvement
Components: Table API & SQL
Affects Versions: 1.4.0
Reporter: Fabian Hueske
Assignee: Fabian Hueske
After a [discussion on the dev mailing
list|https://lists.apache.org/thread.html/735d55f9022df8ff73566a9f1553e14be94f8443986ad46559b35869@%3Cdev.flink.apache.org%3E]
I propose the following changes to the current handling of time indicator
attributes:
* Remove the separation of logical and physical row type.
** Hold the event-time timestamp as regular Long field in Row
** Represent the processing-time indicator type as a null-valued field in Row
(1 bit overhead)
* Remove materialization of event-time timestamps because timestamp is already
accessible in Row.
* Add {{ProcessFunction}} to set timestamp into the timestamp field of a
{{StreamRecord}}.
