CAS Actions

The Cloud Analytic Services (CAS) REST APIs are for data scientists, programmers and administrators, who need to interact with CAS directly and know about CAS actions. There are API operations for executing CAS actions, managing the CAS sessions, monitoring the system and inspecting the CAS grid.

SAS Viya uses CAS to perform tasks. The smallest unit of work for the CAS server is a CAS action. CAS actions can load data, transform data, compute statistics, perform analytics and create output. Each action is configured by specifying a set of input parameters. Running a CAS action in the CAS server processes the action's parameters and the data and creates an action result.
