…OAD/JOIN execution Stateful keyed two-input operator backing LATERAL SNAPSHOT joins. * Two phases (LOAD/JOIN) gated by an operator UnionListState; mixed-phase rescale collapses to LOAD. Flip triggers: build-side WM reaches loadCompletedTime, or a processing-time idle-timeout fallback. * Probe records are buffered in LOAD and joined on flip. Build-side changes are buffered per-key and applied lazily in event-time order on the next per-key access once the build-side WM advanced, preserving atomic -U/+U visibility. * Watermarks: build-side absorbed; probe-side held back in LOAD, forwarded in JOIN. NULL equi-keys filtered via JoinConditionWithNullFilters. * State TTL via keyed processing-time timers with a post-flip grace window; rearms are amortized so effective time-to-eviction is in [1.0×, 1.5×] stateTtlMs. Generated-By: Claude Opus 4.7 (1M context)
… operator Rewrites a join over a SNAPSHOT table function in a LATERAL clause into a dedicated FlinkLogicalLateralSnapshotJoin and converts it to a StreamPhysicalLateralSnapshotJoin / StreamExecLateralSnapshotJoin backed by the LateralSnapshotJoinOperator. The nodes derive their own output row type (materializing the build-side rowtime) and carry the SNAPSHOT arguments as fields. Generated-By: Claude Opus 4.8 (1M context)
Adds ForbidSnapshotOutsideLateralRule, which rejects any SNAPSHOT scan that survives the LATERAL SNAPSHOT rewrite with a clear message instead of failing later in the generic PTF translation. Generated-By: Claude Opus 4.8 (1M context)
…h-down source Wire the existing source.sleep-after-elements / source.sleep-time options into TestValuesScanTableSourceWithWatermarkPushDown Generated-By: Claude Opus 4.8 (1M context)
Adds end-to-end coverage for the LATERAL SNAPSHOT processing-time temporal join: * LateralSnapshotJoinITCase: result tests over HEAP and ROCKSDB backends covering different configurations and input scenarios * LateralSnapshotJoinRestoreTest / LateralSnapshotJoinTestPrograms: savepoint restore tests Generated-By: Claude Opus 4.8 (1M context)
