在processElement方法里面timeout>0的逻辑里面,通过flink提供的定时机制注册了一个ProcessingTimeCallback的回调,那么在超过timout时间就会调用其onProcessingTime方法,在onProcessingTime方法中会调用AsyncFunction中timeout方法 AsyncFunction中timeout方法中调用了ResultFuture对象(实际上就是StreamRecordQueueEntry对象)中Completab...

自定义create function 语法 实现了流与维表的join 支持原生FLinkSQL所有的语法 扩展了输入和输出的性能指标到promethus BUG修复: 维表异步加载数据异常,打印真实错误日志,而不是Async function call has timed out。 JOIN条件超过两个,解析异常。 JOIN没有AS表名时,解析异常。
Akka超时导致,一般有两种原因:一是集群负载比较大或者网络比较拥塞,二是业务逻辑同步调用耗时的外部服务。如果负载或网络问题无法彻底缓解,需考虑调大akka.ask.timeout参数的值(默认只有10秒);另外,调用外部服务时尽量异步操作(Async I/O)。 (4) java.io.IOException: Too many open files ...
