Is your feature request related to a problem or challenge? Please describe what you are trying to do.
Currently ballista uses schedules stage by stage, which is great for fault tolerance, but inefficient for adhoc olap execution. Bubble execution mode is to make ballista more efficient for adhoc olap queries which doesn't require fault tolerance.

Describe the solution you'd like
The detailed design can be found here, welcome to comment and share your thoughts.

Describe alternatives you've considered
No.

Additional context
No.

Very good proposal. Can you add some designs of popular systems such as Presto and Clickhouse for comparison?
