I've set up Flarum to use a MySQL database with group replication enabled. But an error popped up when I tried to make a post.
I found this error in my MySQL log file:
Table posts does not use the InnoDB storage engine. This is not compatible with Group Replication.
I then checked the migration file and found out that the posts table used MyISAM, which is not supported by group replication, so I altered the table engine to InnoDB. Then everything worked fine.
Is this a safe operation? Will it cause any problem when I update Flarum to newer versions?
Thank you for your help in advance!
