Rajat Khandelwal commented on LENS-753: --------------------------------------- Committed. Thanks [~akshaygoyal] > Queue number for queries > ------------------------ > > Key: LENS-753 > URL: https://issues.apache.org/jira/browse/LENS-753 > Project: Apache Lens > Issue Type: Improvement > Reporter: Akshay Goyal > Assignee: Akshay Goyal > Fix For: 2.4 > > Attachments: LENS-753.02.patch, LENS-753.03.patch, LENS-753.04.patch > > > This is to add queue number for queries after they were launched, in order to > give users an idea of the sequence in which their queries were launched. Or > in other words, to give them an idea of how many queries were launched before > them which are still competing for resources with their query. > Giving queue numbers from waiting query collection may not be correct as they > are not consistent. When a candidate query is picked up from waiting state, > it is removed from the collection and checked for cost constraints. If it > fails the constraints, the query is added back to the waiting query > collection. This causes inconsistency in terms of indices of queries within > the collection. Because of this inconsistency, user might see their queue > number increasing. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
