Mohit Arora commented on SLING-10123:
-------------------------------------
[~ashishc], [~marett], should we implement an ExponentialBackoff similar to [0]
or would a simple Thread.sleep() for a specified time (linear backoff) be
sufficient? If we want to use [0], would it make sense to extract it out into a
common bundle which both distribution-journal and distribution-core are
importing?

> Key: SLING-10123
> URL: https://issues.apache.org/jira/browse/SLING-10123
> Project: Sling
> Issue Type: Bug
> Components: Content Distribution
> Affects Versions: Content Distribution Core 0.4.2
> Reporter: Mohit Arora
> Priority: Major
> Fix For: Content Distribution Core 0.4.6
>
>
> In case of recoverable exceptions, distribution agent queue processor does
> not evict the queue item from the processing queue [0]. Rather, the item is
> retried infinitely until either the distribution of the item is successful or
> a non-recoverable exception is thrown for the item. However, since there is
> "something wrong" because of which an exception is thrown in the first place,
> we should add a cool off period before trying to reattempt to distribute the
> same item. This can be achieved through a linear or exponential backoff.
