In MySQL website I see below definition for MySQL Cluster.
MySQL Cluster is a technology that enables clustering of in-memory databases in a shared-nothing system.
I want to use Clustering for a chat application like
viber that there are some
Ejabberd servers, which use MySQL as database.Is it necessary that databases use in-memory tables. according this definition all databases and tables should be in-memory or not?
This is the link of MySQL Cluster definition.
