Resolution: Duplicate
> ML_PREDICT streaming semantic tests fail upsert-key validation
> --------------------------------------------------------------
>
> Key: FLINK-40309
> URL: https://issues.apache.org/jira/browse/FLINK-40309
> Project: Flink
> Issue Type: Bug
> Components: Table SQL / Planner, Tests
> Reporter: Purushottam Sinha
> Priority: Major
>
> All 6 programs in MLPredictSemanticTests fail with ValidationException:
> "Primary key: [id], upsert key: none", demanding an explicit ON CONFLICT
> clause. The class is suffixed *Tests, so it has never executed (FLINK-40308)
> and this went unnoticed for ~6 months.
> Added 2025-11-08 by FLINK-38104; the exception landed 2026-01-30 by
> FLINK-38927 (FlinkChangelogModeInferenceProgram.scala:1228). Pre-existing,
> not a rename artifact: the original class from master fails identically 6/6.
> MLPredictRestoreTest passes only because restore tests replay a pre-compiled
> plan and skip changelog-mode inference.
> Open question: should ML_PREDICT propagate the source's primary key [id] as
> the upsert key (planner gap), or do the 6 programs need ON CONFLICT?
> Fix: decide the above, then rename to MLPredictSemanticTest so it runs.
