Ajay Yadav commented on FALCON-705:
-----------------------------------
Actual use case was that there was a feed which was not getting created. It was
not attended till the time for it's entire retention period duration and hence
all instances were lost. This should not be a problem in most of the cases.
Also, instead of number of instances adding a storage quota based solution
would be better was what we discussed.
> Feed Retention at Instance Level
> --------------------------------
>
> Key: FALCON-705
> URL: https://issues.apache.org/jira/browse/FALCON-705
> Project: Falcon
> Issue Type: New Feature
> Components: retention
> Reporter: Pracheer Agarwal
>
> Currently, while specifying retention in feed we need to give some time unit
> and number of units like hours(6).
> It will be good to have feed retention on instance level like instances(5)
> which shows I want to preserve last 5 instances.
> This feature is useful when whole pipeline starts after some time. So it that
> case we don't have to approximate the retention.
