In the September stable release of SAS Viya, SAS CAS Node Scaling has been introduced.
SAS CAS Node Scaling can be configured to automatically balance the loaded CAS tables across the CAS nodes without the need to restart CAS. Previously existing CAS tables would not be load balanced to use the new workers.
This functionality simplifies the process of managing the number of CAS nodes available to the platform. This means when workload is high the number of nodes can be increased to ensure optimal performance and when workload is low costs can be managed by reducing the number of nodes.
