Hi Chen, 1. Currently, Interpreter binding mode is more like whether each Note will have a separate Interpreter session(scoped/isolated) or not(shared), rather than per user. https://issues.apache.org/jira/browse/ZEPPELIN-1210 will bring interpreter session per user in the Zeppelin server side, but for now, Livy interpreter itself manages session per user.
2. Interpreter Authorization is working on https://issues.apache.org/jira/browse/ZEPPELIN-945. Proposed patch does not distinguish edit/use/restart permission, but we can think about it based on initial work. 3. For now, create multiple interpreter settings with different memory configuration is only approach to do that, i think.
