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


The following database engines are supported:
  • MySQL
  • Redis
  • MongoDB
  • PostgreSQL
  • ApsaraDB RDS for SQL Server
  • PolarDB for MySQL
  • PolarDB for PostgreSQL
  • PolarDB for PostgreSQL (Compatible with Oracle)
  • PolarDB-X 2.0
  • MySQL, Redis, MongoDB, and PostgreSQL databases can be Alibaba Cloud databases or self-managed databases.
  • A database instance belongs to only one cluster.
