背景 基于每次调用的负载均衡 需要注意的是,gRPC的负载均衡发生在每次调用时,而不是每次连接时.换句话说,就算所有的请求来自于同一个客户,我们也希望可以将它们负载均衡到所有的服务器. 负载均衡的方法 在讨论gRPC所使用的负载均衡之前,我们讨论一下常规的负载均衡方式. 代理方式 使用代理作为可信任的客户端,向负载均衡系统发送请求.因为它们需要有RPC请求和回复的临时副本,代理通常需要更多的资源来进行这个操作.这个也会增加RPCs请求的延迟.代理模式在处理heavy services (像存储)…

gRPC Load Balancing 翻译自:https://grpc.io/blog/grpc-load-balancing/ 这是gRPC负载均衡的第一篇,后续会给出基于golang XDS服务发现的例子,了解golang XDS的工作原理. 本文描述了在部署gRPC时可能会采用的几种负载均衡场景. 大规模gRPC部署下,通常会有大量相同的后端实例以及大量客户端.由于每个服务的容量是有限的,因此会使用负载均衡在可用的服务器之间均衡来自客户端的请求. 目录 gRPC Load Balanci…

It seems my pgpool-II does not do load balancing. Why? First of all, pgpool-II' load balancing is "session base", not "statement base". That means, DB node selection for load balancing is decided at the beginning of session. So all SQL…
