Flaviu Cicio updated FLINK-33989: --------------------------------- Description: Given the following Flink SQL tables: {code:sql} CREATE TABLE input ( id STRING NOT NULL, current_value STRING NOT NULL, PRIMARY KEY (id) NOT ENFORCED ) WITH ( 'connector' = 'upsert-kafka', 'topic' = 'input', 'key.format' = 'raw', 'properties.bootstrap.servers' = 'sn-kafka:29092', 'properties.group.id' = 'your_group_id', 'value.format' = 'json' ); CREATE TABLE output ( id STRING NOT NULL, current_value STRING NOT NULL, PRIMARY KEY (id) NOT ENFORCED ) WITH ( 'connector' = 'upsert-kafka', 'topic' = 'output', 'key.format' = 'raw', 'properties.bootstrap.servers' = 'sn-kafka:29092', 'properties.group.id' = 'your_group_id', 'value.format' = 'json' ); {code} And, the following entries are present in the input Kafka topic: {code:json} [ { "id": "1", "current_value": "abc" }, { "id": "1", "current_value": "abcd" } ]{code} If we execute the following statement: {code:sql} INSERT INTO output SELECT id, current_value FROM input; {code} The following entries are published to the output Kafka topic: {code:json} [ { "id": "1", "current_value": "abc" }, { "id": "1", "current_value": "abcd" } ]{code} But, if we execute the following statement: {code:sql} INSERT INTO output SELECT id, current_value FROM input WHERE id IN ('1'); {code} The following entries are published: {code:json} [ { "id": "1", "current_value": "abc" }, null, { "id": "1", "current_value": "abcd" } ]{code} We would expect the result to be the same for both insert statements. As we can see, there is an extra tombstone generated as a result of the second statement. Moreover, if we make a select on the input table: {code:sql} SELECT * FROM input; {code} We will get the following entries: ||op||id||current_value|| |I|1|abc| |-U|1|abc| |+U|1|abcd| We expected to see only the insert and the update_after entries. The update_before is added at DeduplicateFunctionHelper#122. This is easily reproducible with this test that we added in the UpsertKafkaTableITCase from flink-connector-kafka: {code:java} @Test public void testAggregateFilterOmit() throws Exception { String topic = COUNT_FILTER_TOPIC + "_" + format; createTestTopic(topic, 1, 1); env.setParallelism(1); // ------------- test --------------- countFilterToUpsertKafkaOmitUpdateBefore(topic); // ------------- clean up --------------- deleteTestTopic(topic); } private void countFilterToUpsertKafkaOmitUpdateBefore(String table) throws Exception { String bootstraps = getBootstrapServers(); List<Row> data = Arrays.asList( Row.of(1, "Hi"), Row.of(1, "Hello"), Row.of(2, "Hello world"), Row.of(2, "Hello world, how are you?"), Row.of(2, "I am fine."), Row.of(3, "Luke Skywalker"), Row.of(3, "Comment#1"), Row.of(3, "Comment#2"), Row.of(4, "Comment#3"), Row.of(4, null)); final String createSource = String.format( "CREATE TABLE aggfilter_%s (" + " `id` INT,\n" + " `comment` STRING\n" + ") WITH (" + " 'connector' = 'values'," + " 'data-id' = '%s'" + ")", format, TestValuesTableFactory.registerData(data)); tEnv.executeSql(createSource); final String createSinkTable = String.format( "CREATE TABLE %s (\n" + " `id` INT,\n" + " `comment` STRING,\n" + " PRIMARY KEY (`id`) NOT ENFORCED\n" + ") WITH (\n" + " 'connector' = 'upsert-kafka',\n" + " 'topic' = '%s',\n" + " 'properties.bootstrap.servers' = '%s',\n" + " 'key.format' = '%s',\n" + " 'value.format' = '%s'" //+ " 'sink.omit-row-kind' = '-U'" + ")", table, table, bootstraps, format, format); tEnv.executeSql(createSinkTable); String initialValues = "INSERT INTO " + table + " " + "SELECT * " + "FROM aggfilter_" + format + " " + "WHERE id > 2"; tEnv.executeSql(initialValues).await(); // ---------- read from the upsert sink ------------------- final List<Row> result = collectRows(tEnv.sqlQuery("SELECT * FROM " + table), 3); List<String> actual = TestValuesTableFactory.getResults(String.format("%s", table)); List<Row> expected = Arrays.asList( changelogRow("+I", 1L, 1L), changelogRow("+I", 2L, 1L), changelogRow("-D", 2L, 1L), changelogRow("+I", 2L, 2L), changelogRow("+I", 3L, 1L), changelogRow("-D", 3L, 1L), changelogRow("+I", 3L, 2L), changelogRow("-D", 3L, 2L), changelogRow("+I", 3L, 3L), changelogRow("+I", 4L, 1L), changelogRow("-D", 4L, 1L), changelogRow("+I", 4L, 2L), changelogRow("-D", 4L, 2L), changelogRow("+I", 4L, 3L), changelogRow("-D", 4L, 3L)); assertThat(result).satisfies(matching(deepEqualTo(expected, true))); } {code} was: Given the following Flink SQL tables: {code:sql} CREATE TABLE input ( id STRING NOT NULL, current_value STRING NOT NULL, PRIMARY KEY (id) NOT ENFORCED ) WITH ( 'connector' = 'upsert-kafka', 'topic' = 'input', 'key.format' = 'raw', 'properties.bootstrap.servers' = 'sn-kafka:29092', 'properties.group.id' = 'your_group_id', 'value.format' = 'json' ); CREATE TABLE output ( id STRING NOT NULL, current_value STRING NOT NULL, PRIMARY KEY (id) NOT ENFORCED ) WITH ( 'connector' = 'upsert-kafka', 'topic' = 'output', 'key.format' = 'raw', 'properties.bootstrap.servers' = 'sn-kafka:29092', 'properties.group.id' = 'your_group_id', 'value.format' = 'json' ); {code} And, the following entries are present in the input Kafka topic: {code:json} [ { "id": "1", "current_value": "abc" }, { "id": "1", "current_value": "abcd" } ]{code} If we execute the following statement: {code:sql} INSERT INTO output SELECT id, current_value FROM input; {code} The following entries are published to the output Kafka topic: {code:json} [ { "id": "1", "current_value": "abc" }, { "id": "1", "current_value": "abcd" } ]{code} But, if we execute the following statement: {code:sql} INSERT INTO output SELECT id, current_value FROM input WHERE id IN ('1'); {code} The following entries are published: {code:json} [ { "id": "1", "current_value": "abc" }, null, { "id": "1", "current_value": "abcd" } ]{code} We would expect the result to be the same for both insert statements.
