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


The following database engines are supported:
  • MySQL
  • Redis
  • MongoDB
  • PostgreSQL
  • PolarDB MySQL
  • PolarDB PostgreSQL
  • PolarDB Oracle
Note MySQL, Redis, MongoDB, and PostgreSQL databases can be Alibaba Cloud databases or self-managed databases. A database instance can belong to only one cluster.
