根因分析

gRPC 默认最大接收消息大小为 4MB。服务端或客户端收到的序列化消息超过了该限制。常见于 protobuf 中嵌入的大型 repeated 字段或二进制数据。

English

The default gRPC max receive message size is 4MB. The server or client received a serialized message exceeding this limit. Common with large repeated fields or blobs embedded in protobuf.

解决方案

  1. 90% 成功率 
    // server
s := grpc.NewServer(grpc.MaxRecvMsgSize(16 * 1024 * 1024))
// client
conn, _ := grpc.Dial(addr, grpc.WithDefaultCallOptions(grpc.MaxCallRecvMsgSize(16*1024*1024)))
  2. 85% 成功率 
    stream, err := client.Upload(ctx)
for _, chunk := range chunks {
    if err := stream.Send(&pb.Chunk{Data: chunk}); err != nil { return err }
}
resp, err := stream.CloseAndRecv()

无效尝试

常见但无效的做法:

  1. 75% 失败

    The limit applies to the decompressed message size on receive; compression does not change the post-decompression size.

  2. 60% 失败

    Without a defined chunking protocol (e.g., streaming with sequence numbers), the receiver cannot reconstruct the message.
