Upgrade of a set of services dedicated to databases

What’s new?

We have made updates to the services Distributed Database Middleware (DDM), Data Replication Service (DRS), Document Database Service (DDS) and Relational Database Service (RDS) to expand the scope and cover more operations related to database management in the cloud.

Relational Database Service (RDS)

New MySQL features
  • Added Source Backup Region.
  • Enabled modification of the default value of the database parameter block_encryption_mode to aes-128-ecb.
  • Now displays instance classes (for example, general-purpose, dedicated) on the Basic Information page on the console
New PostgreSQL features
  • Supports PostgreSQL 13.6
  • We have removed the restriction that storage space cannot be scaled up during the backup.
