Setup DR for your MySQL InnoDB Cluster

MySQL InnoDB Cluster is the High Availability solution for MySQL. It delivers automatic fail-over and guarantees zero data loss (RPO=0).

RPO: Recovery Point Objective describes the interval of time that might pass during a disruption before the quantity of data lost during that period exceeds the Business Continuity Plan’s maximum allowable tolerance.

Example: our business architecture needs to have RPO=2 minutes. This means that in case of failure, 2 minutes of data can be lost.

However, and we saw this recently in Europe, an entire data center can “disappear” instantaneously… So it’s also important to have a Disaster Recovery plan.

One solution, is to have an InnoDB Cluster (Group Replication) that spans across multiple regions. However, this is often not feasible because of high latency across regions.

Another solution is InnoDB Cluster in one region with Asynchronous …

From MySQL Group Replication to MySQL InnoDB Cluster

I wanted to be brave and I installed MySQL Group Replication manually…. it was painful !

Then I realized that managing those servers and especially deal with MySQL Routers was even more painful !

What are my options now ? Is there a solution or do I need to restart from scratch ?

Asking the answer is already answering it… and once again MySQL Shell at the rescue.

I’ve configured everything manually. I also loaded group_replication and clone plugins and finally after having bootstrapped my Group here is what I have:

mysql> select member_host, member_port port, member_state state, 
       member_role role, member_version version
