Xinyi Yan commented on PHOENIX-5495:
------------------------------------
Can it be done in future releases such as 4.16.1 or 4.17(in case we end up
releasing directly from 4.17 after 4.16)?
> Avoid server-server RPCs when row locks are held inside MetaDataEndpointImpl

> Project: Phoenix
> Issue Type: Improvement
> Affects Versions: 4.15.0, 5.1.0

> At various spots in MetaDataEndpointImpl, we acquire row locks and then while
> locks are held, do server-to-server RPC calls. This can lead to lock
> starvation if RPCs take too long. We should decouple such interactions as
> much as possible.
