What is a .feather file?

The Feather file format is a lightweight, columnar data format designed for fast data transfer between data analysis environments. It's particularly well-suited for use with languages like Python and R. Feather is based on the Apache Arrow columnar memory format, which allows for zero-copy reads and writes, significantly improving performance compared to traditional row-based formats like CSV. The format stores data in a simple, uncompressed manner, focusing on speed rather than storage efficiency. This makes it ideal for situations where data needs to be quickly loaded and processed, such as in interactive data analysis workflows or when passing data between different tools in a data pipeline. Feather files contain metadata describing the data types and structure of the columns, enabling efficient data interpretation. While not intended for long-term archival storage due to the lack of compression, Feather provides a valuable solution for rapid data exchange and manipulation within data science ecosystems.
