Determining capacity and usage for your license

Warning

SingleStore 9.0 gives you the opportunity to preview, evaluate, and provide feedback on new and upcoming features prior to their general availability. In the interim, SingleStore 8.9 is recommended for production workloads, which can later be upgraded to SingleStore 9.0.

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

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

SQL

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?.
