> h2. Motivation
> During the normal course of the KDS and KDF's sink's operation, we will 
> likely encounter many failed persists to the destination due to throttling or 
> otherwise. These are currently logged as warn. Also remove trace level 
> logging in 
> {code:java}
> submitRequestEntries{code}
>  for these sinkWriters.
> *Proposed Solution*
> 1. We would like these messages to be logged as debug.
> 2. It would also be beneficial to adjust the wording to clarify that the 
> entries will be requeued for retry.
> *Files to be changed*
>  * KinesisStreamsSinkWriter
>  ** when a request succeeds with a subset of the records and the remainder 
> needs to be retried
>  ** when the request has failed
>  ** when submitRequestEntries is logging to trace
>  * KinesisFirehoseSinkWriter
>  ** when a request succeeds with a subset of the records and the remainder 
> needs to be retried
>  ** when the request has failed
>  ** when submitRequestEntries is logging to trace
