Nice work! How did you convert csv to parquet? That is the step I currently struggle with, most tools I found require me to run some kind of server part.

The author released a tool called csv2parquet about 3 hours ago: https://github.com/cldellow/csv2parquet

I use Apache drill, selecting from a CSV table into a Parquet table. If you use AWS they now provide the ability to convert also.
