Moon, The new roadmap looks very promising. I am very happy to see security in the list. I have some suggestions regarding Enterprise Ready features:
1. Job Scheduler - Can this be improved? Currently the scheduler can be used with Cron expression or a pre-set time. But in an enterprise solution, a notebook might be one piece of the workflow. Can we look towards the functionality of scheduling notebook's based on other notebooks finishing their job successfully? This requirement would arise in any ETL workflow, where all the downstream users wait for the ETL notebook to finish successfully. Only after that, other business oriented notebooks can be executed. 2. Importing a notebook - Is there a current requirement or future plan to implement a feature that allows import-notebook-from-github? This would allow users to share notebooks seamlessly.
