> Project: Apache Lens
> Issue Type: New Feature
> Reporter: Himanshu Gahlaut

>
> 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.
