comparison chart between percona xtradb cluster mariadb cluster

Hi,

Is there any comparison chart between percona xtradb cluster mariadb cluster that I could refer in terms of featurewise?

Percona XtraDB Cluster is basically Percona Server + Galera and MariaDB Cluster is basically MariaDB + Galera, so you should rather be looking for differences between Percona Server and MariaDB. I am not aware of any direct feature comparison matrix between those, but you may check some differences between Percona Server and stock MySQL here:
https://www.percona.com/doc/percona-server/5.6/feature_comparison.html
Note that you may find MariaDB less compatible with MySQL then Percona Server is. For example you may replicate from MySQL 5.6 to Percona XtraDB Cluster 5.6 using GTID and vice versa, while it is not possible with MariaDB Cluster.

thanks for the explaination.
