[jira] [Commented] (LENS-619) Fair Usage Policy for using Lens

    [ https://issues.apache.org/jira/browse/LENS-619?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14594407#comment-14594407 ] 

Amareshwari Sriramadasu commented on LENS-619:
----------------------------------------------

We should have the policy pluggable through interface and implementations. FIFO can be another policy.

> 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.
