Data Warehouse Flavors

DWS provides storage-compute coupled and decoupled data warehouses. For details about the differences between them, see Data Warehouse Types.

You are advised not to use clusters with low specifications, such as clusters with 16 GB memory and 4 vCPUs, in the production environment. Otherwise, resource overload may occur.

Flavors for Storage-Compute Coupled Clusters

  • A storage-compute coupled data warehouse using cloud disks with a vCPU to memory ratio of 1:8 can be elastically scaled, providing unlimited computing and storage capacity. For details, see Table 1.
  • A storage-compute coupled data warehouse using cloud disks with a vCPU to memory ratio of 1:4 provides high-concurrency, high-performance, and low-latency transaction processing capabilities at low costs based on large-scale data query and analysis capabilities. It is suitable for HTAP hybrid load scenarios and real-time analysis scenarios such as IoT. For details about flavors, see Table 2.
  • A storage-compute coupled data warehouse using local disks cannot be scaled up. You can only increase capacity by adding more nodes. For details, see Table 3.

Step indicates the interval for increasing or decreasing the disk size during cluster configuration change. You need to select a value based on the storage step of the corresponding flavor.

Flavors for Storage-Compute Decoupled Clusters

  • A storage-compute decoupled data warehouse using cloud disks can be elastically scaled, providing unlimited computing and storage capacity. For details, see Table 4.
  • A storage-compute decoupled data warehouse using local disks has a fixed storage capacity that cannot be expanded or modified. You can only increase capacity by adding more nodes. For details, see Table 5.

    When creating a storage-compute decoupled cluster, only the second half of the flavors (for example, 4U16G.4DPU) are shown. The prefixes (dwsx3/dwsax3/dwsk3) in the flavor list indicate the storage-compute decoupled CPU architecture.
