問題描述

還請Gatewayworker 大佬去看看呢，實現(xiàn)思路也比較簡單。
Gateway 內(nèi)部維護一個數(shù)組結構，后續(xù)上線的businessworker 初始化0，后續(xù)誰的連接數(shù)小就優(yōu)先分發(fā)給誰。
分布式部署如果businessworker 性能不足的時候，需要增加幾十個worker干活，新來的客戶端連接會優(yōu)先分配給剛上線businessworker進程，直到他們與運行已久的進程連接數(shù)相同，才會逐個輪訓，最終達到連接數(shù)均勻。

1個Gateway, 32個Worker，1個注冊中心，最終測試結果：
