Review comment:
Instead of doing a shuffle here, I think we should refine the approach
we use to build the list of JSON files. I think what happens now is that we
will take previous 100 version files in every version file and add them to the
list even though each new version file has only one different entry. Will
tables with 2000 snapshots and 100 previous metadata files produce a list with
200000 elements?
