[Enhancement]: transferring connection in proxy should be more proactive #11048

Open volgariver6 opened 1 year ago

Is there an existing issue for enhancement?

[X] I have checked the existing issues.

What would you like to be added ?

we should add a flag to tell the tunnel that the connection to backend should be transferred, rather than wait for the right time to do the transfer. Because the transferring may never happen in a busy state.

Why is this needed ?

In high TPS scenario, the connection transfer is extremely slow

暂时没有太好的方案，等把手头其他issue做完再好好想一下

我觉得这件事还是挺重要的，尤其是serverless实例会自动扩缩容，这会使得扩容的机器很难拿到session

已经写完代码，但是对性能可能有影响，有时间需要再讨论一下
