Question

我正在使用Spring Cloud Stream gcp pub sub，并且从newrelic收到错误消息

这是来自newrelic的堆栈跟踪

错误消息 java.lang.OutOfMemoryError：无法创建新的本机线程

您会看到 io.grpc ，春季云流通过带有线程池的gRPC协议与Pub / Sub通信。

我用于将数据发布到GCP的编码（Spring Cloud Stream）：

source.output().send(new GenericMessage<>(eventSync));

根本原因

我发现了由网络问题引起的问题（应用程序无法按预期方式与gcp pubsub通信，并且等待原因超时，这导致线程池出现瓶颈）。

依赖性

根据docs我没有设置属性spring.cloud.gcp.pubsub.subscriber.executor-threads and spring.cloud.gcp.pubsub.publisher.executor-threads

问题

对于Thread performace，如何在Spring Cloud Stream中处理此问题？

如果我设置spring.cloud.gcp.pubsub.publisher.retry.total-timeout-seconds=5（默认值为0表示无限制），可能会有所帮助？

如果我设置spring.cloud.gcp.pubsub.publisher.retry.max-attempts=2（默认值为0表示无限制），可能会有所帮助？

如果我设置spring.cloud.gcp.pubsub.publisher.retry.max-rpc-timeout-second=5（默认值为0表示无限制），可能会有所帮助？
