Thanks for making an Awesome list! 🙌

It looks like you didn't read the guidelines closely enough. I noticed multiple things that are not followed. Try going through the list point for point to ensure you follow it. I spent a lot of time creating the guidelines so I wouldn't have to comment on common mistakes, and rather spend my time improving Awesome.

I think it would be better under "Big Data" than "Databases".

Also:

Has been around for at least 30 days. (Repository created in January 2024)

-> Has been around for at least 30 days. (Repository created in July 2025)

And maybe, remove "unicorn" at the end of the PR description?

In the README, for the description, maybe use the same as on the official Parquet website:

An open source, column-oriented data file format designed for efficient data storage and retrieval.

And, at the top of the PR description, the PR template mentions:

[Explain what this list is about and why it should be included here]

So, I guess that

Columnar storage file format for efficient data processing and analytics.

is not what is expected. Maybe the following:

The list is about Apache Parquet, a widely used data format in the data engineering ecosystem. Projects like Spark, Pandas, Arrow, DuckDB, DataFusion, Iceberg, GeoParquet highly rely on Parquet, as it's both efficient in storage (compression, encoding) and remote retrieval (columnar storage, filter pushdown).

Thanks for the feedback! I'll update the PR to address all the points:

Changes to make:

1. ✅ Move to "Big Data" section instead of "Databases"
2. ✅ Fix repository creation date (July 2025, not January 2024)
3. ✅ Remove "unicorn" from description
4. ✅ Use official Parquet description from parquet.apache.org
5. ✅ Improve PR description with better context

Will update shortly!
