Manage Clusters

Last Updated: Jun 11, 2020

You can use the cluster management feature of DAS to combine instances of the same database engine into a cluster, and then view the information about these instances such as performance trends, slow log trends, and global storage usage at the cluster level.

Types of database engines

  • MySQL
  • Redis
  • MongoDB
  • PostgreSQL
  • PolarDB MySQL
  • PolarDB PostgreSQL
  • PolarDB Oracle

Among the preceding types of database engines, MySQL, Redis, MongoDB, and PostgreSQL databases can be either ApsaraDB for RDS databases or user-created databases.

A database instance can belong to only one cluster.
