Important

The SingleStore 9.1 release candidate (RC) is available now. It will be promoted to general availability (GA) soon and at that time it will be renamed to SingleStore 10.

In the interim, SingleStore 9.1 RC can be used to preview, evaluate, and provide feedback on the new and upcoming features in SingleStore 10, while SingleStore 9.0 is recommended for production workloads.

Determining capacity and usage for your license

Use SHOW STATUS EXTENDED to view license unit capacity against current usage.

For unit-based licenses, output similar to the following is displayed.

SHOW STATUS EXTENDED LIKE "%capacity%";
+--------------------------+---------+
| Variable_name            | Value   |
+--------------------------+---------+
| License_capacity         | 4 units |
| Maximum_cluster_capacity | 4 units |
| Used_cluster_capacity    | 2 units |
+--------------------------+---------+

Where:

  • License_capacity and Maximum_cluster_capacity reflect the total license unit capacity for the cluster

  • Used_cluster_capacity reflects the number of license units used against this capacity

In this example, two of the four available license units have been used. License units, which are calculated against a host's vCPU, RAM, and persistent cache (block storage) dimensions, only apply to hosts that run leaf nodes. To understand how license units are calculated, refer to What are license units and how do they apply to my cluster?.
