Regards tests for the 'general read replica'
{quote}
I'm confused again.

So I think what we need to test here, is to write a special test which will
clearRegionLocationCache everytime before issuing the actual read/write scan
request, to simulate bad client behavior. The cluster without this feature
should be dead soon and the cluster with this feature should perform much
better. Of course if you put too many loads then no cluster could be alive, but
we only need to prove that, we can perform better.

This is the test I suggested above. You think this is about 'general read
replica'? I really do not want to use rhetorical question(Which is your
favorite way to communicate with me) but here I want to use one "Isn't it about
the load balance of meta lookup?".
{quote}
Sounds good. Lets make a follow-on issue?
{quote}
Why do we need a follow-on issue? I think this is exactly what [~huaxiangsun]
wanted to do above? And the test suggestted above by me is exactly what you
replied? You need to put enough load which could make a single replica slow
then you could see the benefits.
To be honest I still have some concerns, but looking at the current situation,
I really wonder whether it is still worth for me to help on this issue. My
comments on jira can not be understand well(the background is I have helped
this issue starting from the design doc step so I think I know what is the
purpose of this issue), my 'changes requested' flag is just ignored without
confirmation and the commit message even said it was signed of by me.
Thanks.
