Multi-Account Overview

Unlike MySQL, MatrixOne is a database with built-in multi-tenancy capability. In a MatrixOne cluster, accounts can be created using the CREATE ACCOUNT command. Conceptually, each tenant represents a completely independent data space, with all data and operations being isolated from other accounts. When users log in with the tenant’s username and password, they enter a MySQL instance where they can perform various operations such as creating databases and tables without affecting the data of other accounts.

Introduction to accounts

The Account in MatrixOne is part of the permission management system. For more information on the permission management system, see Privilege Management Overview section.

Multi-tenancy has various use cases, including multi-tenancy design in SaaS applications, isolating accounts for subsidiaries of a corporation, and database usage for services in a microservices architecture. For more information on application scenarios, see Multi-Account section in the MatrixOne Feature Overview.

Creating and Using Accounts

1. For developers, creating and using accounts in MatrixOne can be done through SQL statements. For more examples, see Create accounts, Verify Resource Isolation section.
2. For operations personnel working with distributed versions of MatrixOne, it is necessary to configure resource isolation and scaling for accounts, for more information on practical guidelines, see Managing CN Groups with Proxy and Scaling MatrixOne Cluster.

Account-to-Account Publish/Subscribe

In addition to ensuring data and load isolation between accounts, MatrixOne provides a publish/subscribe capability that allows data exchange between accounts. This capability can be used to address data synchronization and large-scale data distribution scenarios. For more information, see Publish-subscribe section.
