[jira] [Updated] (FLINK-39710) Release Testing: Verify FLIP-565: Improve ProcessTableFunctions for late data handling and state access
[ https://issues.apache.org/jira/browse/FLINK-39710?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Yuepeng Pan updated FLINK-39710:
--------------------------------
Description:
The state access part of FLIP-565 has not been implemented yet, so the release testing focuses around late data handling.
Testing instructions:
* Create some append-only source (e.g. Kafka) with some out of order data and a watermark strategy that produces late data
* Create a ProcessTableFunction ([from example|https://nightlies.apache.org/flink/flink-docs-master/docs/dev/table/functions/ptfs/#ordering-guarantees-and-late-events]) and submit a Flink job with it
* Case 1: Check whether that only ordered data enters the PTF and late data is dropped
* Case 2: Check that late data is not dropped when the ORDER BY clause is omitted
* Stop and restore both functions from a savepoint and check whether they are checkpoint correctly
