Apache Arrow is a language-agnostic software framework for developing data analytics applications that process columnar data. It contains a standardized column-oriented memory format that is able to represent flat and hierarchical data for efficient analytic operations on modern CPU and GPU hardware.[2][3][4][5][6] This reduces or eliminates factors that limit the feasibility of working with large sets of data, such as the cost, volatility, or physical constraints of dynamic random-access memory.[7]

Interoperability
editArrow can be used with Apache Parquet, Apache Spark, NumPy, PySpark, pandas and other data processing libraries. The project includes native software libraries written in C, C++, C#, Go, Java, JavaScript, Julia, MATLAB, Python, R, Ruby, and Rust. Arrow allows for zero-copy reads and fast data access and interchange without serialization overhead between these languages and systems.[2]
Applications
editArrow has been used in diverse domains, including analytics,[8] genomics,[9][7] and cloud computing.[10]
Comparison to Apache Parquet and ORC
editApache Parquet and Apache ORC are popular examples of on-disk columnar data formats. Arrow is designed as a complement to these formats for processing data in-memory.[11] The hardware resource engineering trade-offs for in-memory processing vary from those associated with on-disk storage.[12] The Arrow and Parquet projects include libraries that allow for reading and writing data between the two formats.[13]
Governance
editApache Arrow was announced by The Apache Software Foundation on February 17, 2016,[14] with development led by a coalition of developers from other open source data analytics projects.[15][16][6][17][18] The initial codebase and Java library was seeded by code from Apache Drill.[14]
