Cross-language open-source columnar data format and compute infrastructure for high-performance data exchange.
Apache Arrow is an open-source columnar in-memory format and data processing infrastructure enabling efficient data exchange between languages. In research data engineering it can improve data processing efficiency between Python, R, databases and big data tools.
Use cases: high-performance data exchange, columnar data, Python/R data bridging, big data processing, data engineering
Note: Arrow is low-level infrastructure; most users use it indirectly via pandas, Polars, DuckDB or Parquet.
