目前版本可以通过调小下面两个变量来缓解这个问题。 ``` parallel_pipeline_task_num // 一个qurry的并发个数,如果为0则并发数为cpu核心的一半 parallel_exchange_instance_num // 显示一个query exchange后的并发个数 ``` 原因是brpc内部有个限制。 ``` | EAGAIN | 11 | 是 | 同时发送的请求过多。软限,很少出现。 | Resource temporarily unavailable | ``` Doris be 与 be 之间的exchange 是共用一个长连接。 而且上游的所有并发都会给下游的所有并发发送数据。(例如并发为n,则同时有n * n 个rpc请求 这导致并发比较高的情况下就很容易出现这个问题。 -- This is an automated message from the Apache Git Service.
