Subject [jira] [Commented] (FALCON-1661) Similar timestamp is getting added for Falcon instance vertex in GraphDB
Date Tue, 15 Dec 2015 07:15:46 GMT

    [ https://issues.apache.org/jira/browse/FALCON-1661?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15057482#comment-15057482

Peeyush Bishnoi commented on FALCON-1661:
-----------------------------------------

[~ajayyadava] As I have already mentioned, presently in GraphDB when vertex get added it has
a "timestamp" on the basis of Oozie coordinator actual time/created time but not on the nominal
time. I require to do sorting on "timestamp", and ordering of vertices is not coming proper
as many vertices "timstamp" is same . Also I mentioned that sorting on two fields (actual
time and nominal time) can be done but that is not the right solution as entity instances
can have same actual time and nominal time. 

I have suggested just a simple solution to permanently fix it so that "timestamp" should be
unique for each added instance vertex. As currently (and the example I provided) many instance
vertices "timestamp" is not unique. Moreover, instance actual time and nominal time, can be
set as vertex property. 

I hope this answers your question.

> When working on FALCON-1643, I found that same "timestamp" is getting set upon adding
Falcon instances vertices in GraphDB. Due to this while trying to sort the vertices on timestamp
many instances are not getting sorted properly.
