> Fair Usage Policy for using Lens
> After a user has used the lens system beyond fair usage policy, he will get lens features in degraded mode. 
> One of the forms of fair usage policy could be that at any point in time only N queries can be present in RUNNING state for a user. 
> If N queries of a user are in RUNNING state, then a new query submitted by same user will stay in QUEUED state until one of the N queries in RUNNING state have moved to SUCCESSFUL, FAILED, OR CANCELLED state.
