Re: [I] 请问出现这个错误(io.debezium.DebeziumException: Failed to deserialize data of EventHeaderV4{timestamp=1627541881000,)是什么原因? [flink-cdc]

   The same issue was encountered with Flink CDC 3.4.0. It tends to occur when large tables exhibit bad backpressure. Furthermore, data loss problems are sometimes observed after a restart; the situation I encountered was that the target database had more data than the source database, mainly because delete data events were not successfully applied. I suspect this is similar to the 'skip processed event' issue mentioned above.
