Feather is a fast binary columnar file format for storing data frames, designed for efficient read/write and cross-language sharing between Python, R, and Julia. Development has moved into Apache Arrow; this package is now a thin wrapper around pyarrow.feather.

Use cases

  • read and write pandas data frames to disk quickly
  • share data frames between Python and R
  • fast serialization of tabular data
  • store data frames in a columnar binary format
  • exchange data between data analysis languages

When to choose

  • you need fast, language-agnostic data frame persistence
  • you already use the pandas/R data ecosystem
  • you want Arrow-backed columnar storage without heavier formats like Parquet

When to avoid

  • you need a general-purpose serialization format for non-tabular data
  • you want actively developed features - use Apache Arrow directly
  • you need compression-heavy long-term archival storage
