Talend REST with request Scope.

[Anonymous]

I am using Talend open studio for ESB(6.4.1) to develop REST API's.  I am exposing REST endpoints to fetch data from tables. 

Questions:

1.  In Talend, is there a way to store data on the basis of users ? Something like Request scope.
2.  Can i have a variable which stores values on the basis of each request ? (unlike 'context' which is throughout application scope )
3. How can i achieve this:
   If user A access the endpoint i connect to database A, if user B access the endpoint i connect to database B?

If you know that User A is making request, via headers or similar, sure, read that value and save it. Then, You can have a logic which will connect to a different DB. We use this all the time.
