I have a simple question .
I have an application which has too many register at the same time .
I want to know is there any solution to multi master and insert only to one node ?
Hi, I am not sure if I understand your question.
PXC is multi-master by default, but it is up to you whether you will write to one node or more at a time.
You may also employ intermediate layer to direct traffic accordingly, like ProxySQL for example.
