Apache Arrow is a cross-language development platform for in-memory data. It specifies a standardized language-independent columnar memory format for flat and hierarchical data, organized for efficient analytic operations on modern hardware. It also provides computational libraries and zero-copy streaming messaging and interprocess communication. Languages currently supported include C, C++, Java, JavaScript, Python, and Ruby.

Apache Arrow™ enables execution engines to take advantage of the latest SIMD (Single input multiple data) operations included in modern processors, for native vectorized optimization of analytical data processing. Columnar layout is optimized for data locality for better performance on modern hardware like CPUs and GPUs.

The Arrow memory format supports zero-copy reads for lightning-fast data access without serialization overhead.

Flexible

Arrow acts as a new high-performance interface between various systems. It is also focused on supporting a wide variety of industry-standard programming languages. Java, C, C++, Python, Ruby, and JavaScript implementations are in progress and more languages are welcome.

Advantages of a Common Data Layer

Roulib Guess Guess Marine Roulib Marine Roulib Marine Guess Roulib Guess Each system has its own internal memory format
70-80% computation wasted on serialization and deserialization
Similar functionality implemented in multiple projects

All systems utilize the same memory format
No overhead for cross-system communication
Projects can share functionality (eg, Parquet-to-Arrow reader)
