Is group replication available in Mysql community? Group replication for Mysql server seems to be a great functionnality.
It is available from version 5.7.17 of MySql Enterprise and Cluster CGE edition.

But is it available for Mysql community ? and starting which version ?

Thanks
Based on the MySQL Developer manual:

https://dev.mysql.com/doc/refman/5.7/en/group-replication-requirements.html

It appears that so long as you're on the appropriate version you'll have access to this feature.
