2126 Caused by: java.util.concurrent.TimeoutException: Invocation of [RemoteRpcInvocation(TaskExecutorGateway.triggerCheckpoint(ExecutionAttemptID, long, long, CheckpointOptions))] at recipient [akka.tcp://flinknode-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.

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.timeout60min;
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 col2col6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.enabledtrue;set table.exec.mini-batch.allow-latency10 s;set table.exec.mini-batch.size5000;set table.optimizer.agg-phase-strategyTWO_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/
