2126 Caused by: java.util.concurrent.TimeoutException: Invocation of [RemoteRpcInvocation(TaskExecutorGateway.triggerCheckpoint(ExecutionAttemptID, long, long, CheckpointOptions))] at recipient [akka.tcp://flink@node-group-1jpmk0002.mrs-qrmc.com:32331/user/rpc/taskmanager_0] timed out. This is usually caused by: 1) Akka failed sending the message silently, due to problems like oversized payload or serialization failures. In that case, you should find detailed error information in the logs. 2) The recipient needs more time for responding, due to problems like slow machines or network jitters. In that case, you can try to increase akka.ask.timeout.

作业优化调整
初步优化
- 根据上述3个原因，并且不存在数据倾斜的情况，适当增加内存，增加checkpoint超时/间隔时间，akka请求超时时间
-- 增加内存
set 'taskmanager.heap.size' = '5092MB';
-- 增加checkpoint间隔/超时时间
set 'execution.checkpointing.timeout'='60min';
set 'execution.checkpointing.interval' = '10 s';
-- 增加异步通信时间
set 'akka.ask.timeout' = '30 s';
- 优化发现仍然未解决上述问题，再次查看flink-sql作业，发现仍然看到任务不断attempt，进一步分析发现flink-sql 数据流和外部维表进行join时耗时较久，将维表去除进行测试，发现反压很快消失确定问题方向后，进行针对性
二次优化
- 根据发现的问题后，一是内存溢出，尽量减少维表数据量，根据业务需求、数据建模需要，只选择必须字段加工新的维表，减少join时的缓存数据量
如 维表 dim_a 有 col1,col2,col3,col4,col5,col6,确认只需要,col2，,col6，，则可以加工出 col2，col6的维表
- 对指标计算，为减少数据计算，利用两阶聚合(先分桶和 group key聚合,再根据group key进行聚合)优势，minibatch(批次计算)优势，在牺牲较低延迟的基础，批次计算指标后，计算效率得到大幅提升，优化前 运行4d 40min 仍存在反压，优化后35min后，反压完全消失
set 'table.exec.mini-batch.enabled'='true';
set 'table.exec.mini-batch.allow-latency'='10 s';
set 'table.exec.mini-batch.size'='5000';
set 'table.optimizer.agg-phase-strategy'='TWO_PHASE';
优化对比
- 优化前

- 优化后
- 从下图发现，经过两阶聚合后，左边经过mini-batch,两阶聚合优化后，处理数据量明显减少
总结
- 定位问题时，需要根据具体日志信息进行分析，结合flink运行原理和监控页面一步步定位出现问题蒜子
- 参考文档 https://nightlies.apache.org/flink/flink-docs-release-1.17/docs/dev/table/tuning/
