Hi guys,
I already have installed ORS cluster of ORS 2 nodes primary-backup successfully on my Lab. But, I would like to installation ORS cluster of ORS 4 nodes(4 Primary, 2 Primary on one data center).
Is there anyone who can help me explain a few questions as below:
1. How to URS chose ORS to work with it? While both two ORS are running primary? I understand for the scenarios ORS using primary- backup on one data center. URS always working with ORS primary, then it will work with ORS backup if ORS primary failed.
2. I know Cassandra stores information regarding active sessions, as well as scheduled activities, but when I'm checking logs ORS as well as select data from DB of Cassandra. I didn't find any data here.
Logs:

cqlsh:orchestration> select * from session;
