> The ReliableSpoolingFileEventReader reads the oldest file in the spooling 
> directory first. This is done by listing the directory contents and then 
> sorting file list based on timestamp. This may be very slow if there are a 
> lot of files (of the order of 100K or more) in the directory.
> However, this is not always needed, there can be simple cases in which the 
> order to consume the file is not important.
> There should be an option of consuming the files in arbitrary order, allowing 
> the files to be consumed quickly without any delay.
