MartijnVisser opened a new pull request, #29241:
URL: https://github.com/apache/flink/pull/29241
## What is the purpose of the change
* `JoinSemanticTests[anti-join-on-nested]` asserts the raw changelog, so it
fails whenever the
anti join transiently emits and retracts `+I[test_same]`. It failed 11 of
the 16 release-2.3
nightlies between 2026-09-10 and 2026-09-17 (8 on Azure, 8 on GitHub
Actions) and the push run
of `e10aab797f` (https://github.com/apache/flink/actions/runs/35220462243)
## Brief change log
* The `anti-join-on-nested` sink asserts the materialized result instead of
the raw changelog,
like the other program in the file
* Not a cherry-pick: master got the line from FLINK-39695 (`4f8b4a88b1e`),
which also copies
Calcite classes into the planner and does not belong on a patch branch
* The companion PR makes the same change on release-2.2; release-1.20 does
not have this test
## Verifying this change
This change is already covered by existing tests, such as
`JoinSemanticTests`.
* each variant compiled once with `./mvnw -o -pl
flink-table/flink-table-planner test
-Dtest=JoinSemanticTests`, then looped with `surefire:test`, JDK 17, under
CPU
load: 21 of 103 runs failed on `cf7fbd3317d`, 0 of 100 with this commit
applied
* changing `NOT EXISTS` to `EXISTS` makes the patched test fail, so the
assertion still catches a
regression
