Sometimes when people discover or extensively use something they are eager to share in contexts they think are relevant. There is an issue when those contexts become too broad.

3 times across 3 months is hardly astroturfing for big parquet territory.

FWIW I am the same. I tend to recommend BigQuery and AWS/Athena in various posts. Many times paired with Parquet.

But it is because it makes a lot of things much simpler, and that a lot of people have not realized that. Tooling is moving fast in this space, it is not 2004 anymore.

His arguments are still valid and 86 days is a pretty long time.

I've downloaded many csv files that were mal-formatted (extra commas or tabs etc.), or had dates in non-standard formats. Parquet format probably would not have had these issues!

no need to be so suspicious when its an open standard not even linked to a startup?
