Upsert-kafka sink doesn’t require planner to send UPDATE_BEFORE messages (planner may still send UPDATE_BEFORE messages in some cases), and will write INSERT/UPDATE_AFTER messages as normal Kafka records with key parts, and will write DELETE messages as Kafka records with null values (indicate tombstone for the key). In order to check if everything is working properly, we can take advantage of the docker logs tool to analyse the output being generated on each container. Flink Cluster: a Flink JobManager and a Flink TaskManager container to execute queries. Username' = 'root' -- user name 'connector. It first reads data from Kafka, then does some simple computation, and writes the results back to Kafka. 'connector' = 'kafka', 'kafka.topic' = 'test-topic', 'format' = 'json', // the value would be a default prefix, as described in FLIP-95 'json.ignore-parse-errors' = 'true' However, all the properties in the WITH clause are connector specific, including the formats.
