autophagy opened a new pull request, #28212:
URL: https://github.com/apache/flink/pull/28212
## What is the purpose of the change
The PTF Test Harness currently does not support any use of state. This PR
adds support for PTFs with state (map, list and pojo) and injects the state
into the eval of the PTF being tested (based on the partition key/s). When eval
completes, the state is then converted into an internal format
(Map/List/RowData) to also provide testing of state serialization.
It currently doesn't support state TTL.
## Brief change log
- Added state support for ProcessTableFunctionTestHarness.
- Refactored some minor things (argument info, how scalar argument values
are stored/handled)
## Verifying this change
This change added tests and can be verified by the state tests in
`ProcessTableFunctionTestHarnessTest`.
