根因分析

客户端在短时间内发送了太多请求，超过了服务器的速率限制。

English

The client has sent too many requests in a short period, exceeding the server's rate limit.

解决方案

  1. 90% 成功率 Honor the retry-after duration and implement backoff. 
    for {
    resp, err := client.SomeRPC(ctx, req)
    if err == nil { return resp }
    if st, ok := status.FromError(err); ok && st.Code() == codes.Unavailable {
        // Extract retry-after from metadata or message
        time.Sleep(30 * time.Second)
        continue
    }
    return err
}
  2. 85% 成功率 Implement client-side rate limiting to avoid hitting server limits. 
    limiter := rate.NewLimiter(rate.Limit(10), 1) // 10 requests per second
for {
    err := limiter.Wait(ctx)
    if err != nil { return err }
    resp, err := client.SomeRPC(ctx, req)
    if err == nil { return resp }
}

无效尝试

常见但无效的做法:

  1. Ignore the retry-after header and keep sending requests. 100% 失败

    The server will continue to reject requests until the rate limit resets.

  2. Increase the rate limit on the client side only. 95% 失败

    Rate limiting is enforced by the server; client-side changes don't affect it.
