Hi @mxm! Thank you very much for your suggestions. Following your advice, I added a version number to SortKeySerializer through restoreSerializer, implementing different serialization methods for v1 and v2. Based on the performance in the test job, the TaskManager chieve state compatibility. However, the JobManager fails to recover due to the DataStatisticsCoordinator, which leads to a failure to start because the SortKeySerializer used in CompletedStatisticsSerializer and GlobalStatisticsSerializer is instantiated directly. This results in a failure when trying to parse the v1 state with the v2 version. Additionally, these two serializers do not change after the Coordinator is initialized. Given this scenario, do you have any good suggestions? -- This is an automated message from the Apache Git Service.
