Assignee: Roman Boyko
> Hash collision inside MiniBatchStreamingJoin operator
> -----------------------------------------------------
>
> Key: FLINK-35184
> URL: https://issues.apache.org/jira/browse/FLINK-35184
> Project: Flink
> Issue Type: Bug
> Components: Table SQL / Runtime
> Affects Versions: 1.19.0
> Reporter: Roman Boyko
> Assignee: Roman Boyko
> Priority: Major
> Labels: pull-request-available
>
> The hash collision is possible for InputSideHasNoUniqueKeyBundle. To
> reproduce it just launch the following test within
> StreamingMiniBatchJoinOperatorTest:
>
> {code:java}
> @Tag("miniBatchSize=6")
> @Test
> public void testInnerJoinWithNoUniqueKeyHashCollision(TestInfo testInfo)
> throws Exception {
> leftTypeInfo =
> InternalTypeInfo.of(
> RowType.of(
> new LogicalType[] {new IntType(), new
> BigIntType()},
> new String[] {"id1", "val1"}));
> rightTypeInfo =
> InternalTypeInfo.of(
> RowType.of(
> new LogicalType[] {new IntType(), new
> BigIntType()},
> new String[] {"id2", "val2"}));
> leftKeySelector =
> HandwrittenSelectorUtil.getRowDataSelector(
> new int[] {0},
> leftTypeInfo.toRowType().getChildren().toArray(new
> LogicalType[0]));
> rightKeySelector =
> HandwrittenSelectorUtil.getRowDataSelector(
> new int[] {0},
> rightTypeInfo.toRowType().getChildren().toArray(new
> LogicalType[0]));
> joinKeyTypeInfo = InternalTypeInfo.of(new IntType());
> super.beforeEach(testInfo);
> testHarness.setStateTtlProcessingTime(1);
> testHarness.processElement2(insertRecord(1, 1L));
> testHarness.processElement1(insertRecord(1, 4294967296L));
> testHarness.processElement2(insertRecord(1, 4294967296L));
> testHarness.processElement2(deleteRecord(1, 1L));
> testHarness.close();
> assertor.shouldEmit(testHarness, rowOfKind(RowKind.INSERT, 1,
> 4294967296L, 1, 4294967296L));
> } {code}
