监控Apache Flink应用程序(入门)and publish transactions upon successful checkpoints of Flink, adding latency usually up to the checkpointing interval for each record. In practice, it has proven invaluable to add timestamps to your events as latency & throughput of your application are in line with your expectations and it is checkpointing consistently, this is probably everything you need. On the other hand, if you job’s performance significantly, this can usually be attributed to the size of your application state (check the checkpointing metrics $ ^{5} $ for an estimated size of the on-heap state).
