Apache Arrow

Apache Arrow is a development platform for in-memory analytics. It contains a set of technologies that enable big data systems to process and move data fast. It specifies a standardized language-independent columnar memory format for flat and hierarchical data, organized for efficient analytic operations on modern hardware.

The project is developing a multi-language collection of libraries for solving systems problems related to in-memory analytical data processing. This includes such topics as:

  • Zero-copy shared memory and RPC-based data movement
  • Reading and writing file formats (like CSV, Apache ORC, and Apache Parquet)
  • In-memory analytics and query processing
