It explains the problem's cause based on replica identity settings and introduces solutions, starting with Debezium's built-in reselect postprocessor. It then explores more advanced, stateful stream processing approaches using Apache Flink's DataStream API, Flink SQL with OVER aggregation, and the new Process Table Functions (PTFs) in Flink 2.1.
