New Distributed Database Middleware (DDM) service in region EU-DE

Distributed Database Middleware (DDM) is a MySQL-compatible, distributed middleware service designed for relational databases. It can resolve distributed scaling issues to break through capacity and performance bottlenecks of databases, helping handle highly concurrent access to massive volumes of data.

DDM utilises a decoupled compute and storage architecture and provides features such as database and table sharding, read/write partitioning, elastic scaling and sustainable operations and maintenance functions.

Advantages:

  • Automatic Database and Table Sharding
    DDM supports automatic database and table sharding to distribute data across multiple data nodes, so impacts on your services are greatly reduced once a fault occurs. It also supports explosive growth of services.
  • Read/Write Splitting
    DDM can leverage data nodes. If there is still great query pressure after horizontal sharding, you can enable read/write splitting to speed up database processing and access, without the need to reconstruct your service system.
  • Elastic Scaling
    MySQL databases can support only medium- and small-scale service systems because their CPU, memory, and network processing are limited by server configurations and their storage depends on the size of SSD or EVS disks.

DDM supports both compute and storage scaling. You can add nodes to a DDM instance or scale up its node class. Alternatively, increase shards or data nodes to distribute data from one large table to multiple tables or scale out storage resources as services grow, without worrying about O&M.

Further information can be found in the DDM area of the Help Center or DDM Landingpage.
