PXC scale


How big PXC scale can be?
I mean, PXC is right DBMS to deal with PB sized data like HBase?

Also, is there any use case of PXC with large scale data.

PXC is nothing but a cluster of MySQL (Percona Server) database.
I am not sure if user has tried scaling MySQL to PB scale and same will be inherited by PXC too though I don’t recall of any restriction as such.
