You can assign a database to a specific resource group when creating it. Once assigned, all streaming jobs for that database will run only on the compute nodes within the designated group. This mechanism provides two primary benefits:
  • Granular fault isolation: If a CN within resource-group-a crashes, only the databases assigned to resource-group-a are affected. Databases in other resource groups remain unaffected.
  • Workload matching & performance optimization: You can tailor resource allocation to match the specific needs of different workloads.

​
Manage resource groups

Navigate to the project overview page. Select Resources in the sidebar to create new resource groups and manage existing ones.
  • To add a new resource group, click Create resource group in the top-left corner. Enter the resource group name and select the desired machine size and replica count.
  • To access operations for an existing resource group, hover over the desired entry, Delete and Edit buttons will appear on the right.

​
Manage databases

On the same Resources page, click Databases tab on the top bar to create a new database in a resource group or manage existing databases.
  • To create a new database, click the Create database in the top-left corner, enter the database name, and select the desired resource group. To create a database on the default compute nodes, select the default resource group.
  • Hover over a database entry to delete it from its assigned resource group.
