In the SAS© Viya™ platform, you can store user-defined formats in catalogs for use in a SAS© session, or you can store them in a format library on the CAS server. Format libraries are associated with a CAS session, or they can be promoted to global scope to be available to all CAS sessions. User-defined formats in a format library are server-side formats that the server uses when an analysis is performed based on formatted values. You can migrate existing user-defined formats from SAS© to the SAS© Viya™ platform. For more information, see SAS© Cloud Analytic Services: User-Defined Formats.

« When performing data-intensive tasks like a groupby or aggregation in CAS, using server-side formats is significantly more efficient than pre-processing data into strings. It allows the server to group the raw, smaller data values while only using the formatted labels for the final output, saving both memory and CPU cycles. »
