Naman Mishra commented on LIVY-666:
-----------------------------------

[~jerryshao] Thanks for reviewing the plan. As mentioned above, statement 
related APIs will need to be slightly changed as follows. Will keep the APIs 
backward compatible.
 * Statement creation (POST <session-id>/statements)[Must have]: Optional 
parameter "interpreterGroup" to specify the context of execution of this 
statement. If unspecified, we can default to a "default" interpreter group. 
Backward compatibility is maintained with the default context.
 * Statement retrieval (GET <session-id>/statements or /statement/<id>)[Nice to 
have]: Additional attribute "interpreterGroup" in response to identify the 
execution context of statement. This should be backward compatible as well.
 * Listing of interpreter groups [Nice to have]: Implement new API to list all 
existing interpreter groups under a session to help with debugging purposes.

> Support named interpreter groups

> Currently, a session can contain only one interpreter group. In order to 
> support use case of multiple repls with the same spark application multiple 
> interpreters with different variable scoping (something similar to scoped 
> interpreter mode in Zeppelin: 
> [https://zeppelin.apache.org/docs/0.8.0/usage/interpreter/interpreter_binding_mode.html#scoped-mode
>  
> |https://zeppelin.apache.org/docs/0.8.0/usage/interpreter/interpreter_binding_mode.html#scoped-mode]),
>  I propose to have "named interpreter groups", i.e., multiple interpreter 
> groups in a session all sharing a spark context. The interpreter group can be 
> specified on which the execution is supposed to happen in the execution API.
> Similar ask has been put in LIVY-325
