Key Concepts

In SelectDB, organization is the billing unit. Each organization will be billed individually. We recommend that you divide organizations by cost unit. One user can be affiliated to multiple organizations. Multiple warehouses can be created under one organization.

Each warehouse adopts an architecture that separates storage and computation. The data will be stored on object storage of cloud providers. In one warehouse, you may create multiple clusters that are isolated from each other. Each cluster consists of multiple nodes, and all clusters share the same object storage.
