[GitHub] [incubator-brpc] kof02guy opened a new issue, #1976: 请问在使用single这种连接方式时，如何限制服务端的最大连接数

对于连接池来说，有max_connection_pool_size。而对于baidu_std默认的single这种方式，是否有方法去限制服务端创建的最大连接数呢？

max_connection_pool_size 的话只是限制一个连接池常驻链接的数量，实际建立的连接数取决于并发数量，brpc作为客户端底层建立的tcp连接会尽量共享的。

max_connection_pool_size是限制客户端连接数的。
single模式，每个后端server（ip+port）只会建立一个连接。所以只要限制server个数，就可以限制客户端的连接数。
服务端的连接数目前无法限制

连接数一般来说没什么影响，只要不超过linux本身limit限制即可。
对服务可用性影响更大的是并发请求数，这个一般通过ServerOptions的max_concurrency来限制

max_concurrency跟连接没关系，它限制的是并发处理的请求数。
