Scale a project manually

After creating a project, you have the flexibility to scale its resources and capacity to meet your specific data processing and analysis needs. This can be achieved through two methods: increasing or decreasing the number of worker nodes (horizontal scaling) or adjusting the resource capacity of each node in the project (vertical scaling).

note

You can scale the projects created in the Standard plan and the Advanced plan. The Trial plan has a fixed number of nodes and resources.

Scale your project​

To scale your project:

  1. Navigate to the project details page.

  2. Click Configuration details > Re-scale to access the scaling options.

Configure node resources​

When scaling, you will configure the vCPU numbers for each component, with the memory size automatically scaling at a 1:4 ratio with the vCPUs. The RWU numbers are calculated based on the vCPU and memory size.

  • Compute node
    • RWU options: 2, 4, 8, 16
    • You can have between 1 to 5 compute nodes in a project.
  • Frontend node
    • RWU options: 1, 2, 4
    • You can have between 1 to 5 frontend nodes in a project.
  • Meta node
    • RWU options: 1, 2, 4, 8, 16
    • Only one meta node is allowed per project.
  • Compactor node
    • RWU options: 1, 2, 4, 8, 16
    • You can have up to 2 compactor nodes in a project.

For detailed information on each node, see Understanding nodes in RisingWave.
