Hey @Wouter0100 !
Thanks for reporting this, I think this is a quite interesting feature, it could potentially save costs in infrastructure and provide more resiliency to the MariaDB cluster.
Regarding the implementation, I'm not sure how to implement this, as we would need a different Docker image for the Galera Arbitrator, it's not packaged in the official MariaDB images by default. The thing is that mariadb-operator
reconciles MariaDB
resources into StatefulSet
with multiple replicas with the same Docker image. If I understood it correctly, some nodes would be arbitrators instead of MariaDBs, which would mean that some replicas would run the arbitrator image instead of the MariaDB one.
I will try to re-think how to implement this, suggestions are more than welcome 🙏🏻
Thanks for bringing this up
from mariadb-operator.
Thanks for your response @mmontes11.
Would an alternative resource be an option? For example, an Arbitrator
-resource referencing a MariaDB
-resource.
from mariadb-operator.
That could be an option @Wouter0100 !
This new Arbitrator
resource would be reconciled intro another StatefulSet
that is part of the MariaDB cluster.
We will consider this when we start working on the Galera support , stay tuned!
