Turning Off Unused Compute Resources
While you can delete a compute stack at any time without loss of data, it is often be useful to instead temporarily turn down unused compute capacity in a Datomic system. This is achieved by setting the scaling capacity targets for your compute group's auto scaling group to 0:
Adjusting the ASG
CLI Tools - Solo Topology
Select your stack (query group or primary compute group) in the Auto Scaling Group Console and click the "Edit" button:
In the dialog box that appears, set the Desired Capacity, Min, and Max to 0 and click "Save".
The ASG will terminate all nodes of that compute or query group without removing any of the other system resources. When you wish to re-activate your capacity, edit the same ASG and set the scaling capacity targets back to their original values.
