What’s the latest on using Nextcloud with Galera? Having a multi-master DB cluster is the best way to have a highly available and load-balanced cluster within a DC yet last I checked, this wasn’t supported.
This forum news posts mentions Galera support without any technical information on how to set it up.
I ask now since Nextcloud 14 is on the way. I’m hoping something has changed.
For those not familiar with the issue, a multi-master Galera cluster requires the transaction isolation level to be
REPEATABLE-READ. According to the Nextcloud docs, the isolation level
READ COMMITED needs to be set for the database. As these are conflicting, multi-master Galera cannot be used with Nextcloud.
