Apache Flink 检查点与保存点实践

# Apache Flink 检查点与保存点实践 ## 配置片段（flink-conf.yaml） ``` state.backend: filesystem state.checkpoints.dir: file:///tmp/flink-checkpoints execution.checkpointing.interval: 1m ``` ## CLI 操作 ``` flink savepoint file:///tmp/flink-savepoints flink cancel -s file:///tmp/flink-savepoints/ ``` ## 总结 合理的检查点与保存点策略可提升流作业的容错与演进能力。
