根因分析
客户端 gRPC 流多路复用超出了每个 HTTP/2 连接配置的最大并发流限制(默认 100)。
English
Client-side gRPC stream multiplexing exceeds the configured maximum concurrent streams limit (default 100) per HTTP/2 connection.
官方文档
https://grpc.io/docs/guides/performance/#connection-concurrency解决方案
-
通过通道配置增加客户端最大并发流数:Go 中使用 `grpc.ChannelConfig{MaxConcurrentStreams: 200}`,C++ 中使用 `withMaxConcurrentStreams(200)`。 -
创建多个 gRPC 通道以将流分布到多个连接上。每个通道都有自己的 HTTP/2 连接。
无效尝试
常见但无效的做法:
-
Increasing server-side max concurrent streams
95% 失败
The error is client-side; server config doesn't affect client limits.
-
Restarting the client without code changes
90% 失败
The limit is hit again under the same load pattern.
-
Disabling HTTP/2 flow control
85% 失败
Flow control and stream limits are separate; disabling flow control doesn't increase stream count.
