> I am proposing to add a new function in Dataset class to fix small file
> problem. We have noticed that if the source data our spark job reads have
> many small files (KB size), it creates lot of partitions. This PR adds a new
> function named optimizePartition which when used creates partitions of size
> 128MB if no desired partition's size passed. You can pass your own desired
> partition size.

> article on Medium where I detailed the test I did and result I achieved.
