Questions of working with CAS

[huylegq]

Hi all,

I'm new SAS Viya user and studying programming on CAS. I would like to ask some questions regarding to this topic. Could you please kindly help to take a look and give me some hints. 

CAS management

1. If anyone can load data to CAS, how to manage the data volume can be loaded to CAS memory?
2. How can SAS Viya Admin control global scope CAS tables automatically?
3. How to change scope (session to global and vice versa) of existing in-memory CAS tables?

DATA Step to Run in CAS

1. With DATA step using BY statement to process CAS tables, how much data can be distributed to one thread? What if a group have more data than what a thread can handled?
2. Should we optimize and How to optimize performance if some threads might need to process a number of rows and others might not?

Thank you all!!!
