Subject [jira] [Commented] (FALCON-721) Add SLA for Feeds
Date Tue, 28 Oct 2014 15:29:34 GMT

    [ https://issues.apache.org/jira/browse/FALCON-721?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14186953#comment-14186953

Ajay Yadav commented on FALCON-721:


I think sla has no natural association with feed retention and hence there should be no validation
on basis of that. e.g. we might want to move to a disk quota based retention and in such case
it will not be possible to have sla to be associated with that. 

I agree with you that having a slaHigh more than retention limit doesn't make much sense but
this doesn't break anything in the system. sla values are supposed to be watermarks against
which the user wants to get the metrics and should follow garbage in garbage out.
