That's cute. :)
There isn't much value in feeding it all into a conventional RDBMS. OLAPs and columnar stores are what is needed here. But first it will need a great deal of grooming and ETL work.
Yeah.. It would be much easier to copy the data to S3/any object storage (better to convert it into a columnar format like parquet) and query it directly using a SQL on lake engine like Dremio or Athena or S3Select would work too.
