Support for alternative clusters

[federico-razzoli]

Let's discuss the section "Support for alternative clusters", in APPENDIX C.

Should we support more cluster types? Would it be acceptable to use Galera with Percona Server instead of InnoDB Cluster with MySQL? Would it be acceptable to use Codership Oy MySQL + Galera builds?

If a user wants to use MySQL Enterprise or they just really want to stick to vanilla community MySQL, I'm not sure that MySQL + Galera is a suitable alternative. There are a variety of reasons why customers might want vanilla MySQL 8. Supporting group replication/innodb cluster is probably desirable in that case, but you would probably need to find a customer willing to use it and test it to make developing the support worthwhile.

Thanks, @greenlion. To be clear, I'm not strictly against supporting InnoDB Cluster. But as you said it must be worthwhile.
