Label:When? Why? With MySQL cluster? Reduce data center node pressure and large data processing (read/write separation), using MySQL distribution, one or more application corresponding to a MySQL database. Make shared data from several MySQL databases, such as shopping carts, user objects, etc., in the presence of data nodes. Other data that is not shared are also maintained in the MySQL database itself, which is distributed separately.
