> When the \{{AbstractSharedCachingDataStore#getRecordIfStored}} is called and
> if the cache load returns an error from backend then the stream is directly
> retrieved from backend and returned. This stream should first be downloaded
> to the temp dir configured and then stream returned over that. If the
> consuming applications don't close the stream then there's chance of
> connection pool to the backend getting starved.
