ApsaraDB for MongoDB:Replica set instance types

Last Updated:Jun 13, 2024

This topic describes the available instance types of ApsaraDB for MongoDB replica set instances.

Note
  • The supported memory capacity includes the memory that is occupied by the management services in ApsaraDB for MongoDB, the database service, and the underlying operating system (such as the BIOS, the kernel of the operating system, and the hypervisor). Therefore, the available memory may be less than the memory capacity that is supported by the instance type.

  • Some instance types were upgraded on May 14, 2024. If the maximum number of connections to your instance is different from that described in this topic, you can restart the instance. For more information, see [Notice] The maximum number of connections to ApsaraDB for MongoDB instances of specific specifications is increased.

Instances that use cloud disks

The following database engine versions are supported:

  • MongoDB 7.0

  • MongoDB 6.0

  • MongoDB 5.0

  • MongoDB 4.4
