| <h2>What is Arrow?</h2> |
| <div class="row"> |
| <div class="col-lg-4 mt-3"> |
| <h3>Format</h3> |
| <p>Apache Arrow defines a language-independent columnar memory format for flat and hierarchical data, organized for efficient analytic operations on modern hardware like CPUs and GPUs. The Arrow memory format also supports zero-copy reads for lightning-fast data access without serialization overhead.</p> |
| <p><a href="/overview/">Learn more</a> about the design or |
| <a href="/docs/format/Columnar.html">read the specification</a>.</p> |
| </div> |
| <div class="col-lg-4 mt-3"> |
| <h3>Libraries</h3> |
| <p>Arrow's libraries implement the format and provide building blocks for a range of <a href="/use_cases/">use cases</a>, including high performance analytics. <a href="/powered_by/">Many popular projects</a> use Arrow to ship columnar data efficiently or as the basis for analytic engines.</p> |
| <p>Libraries are available for <a href="/docs/c_glib/">C</a>, <a href="/docs/cpp/">C++</a>, <a href="https://github.com/apache/arrow/blob/main/csharp/README.md">C#</a>, <a href="https://godoc.org/github.com/apache/arrow/go/arrow">Go</a>, <a href="/docs/java/">Java</a>, <a href="/docs/js/">JavaScript</a>, <a href="/julia/">Julia</a>, <a href="https://github.com/apache/arrow/blob/main/matlab/README.md">MATLAB</a>, <a href="/docs/python/">Python</a>, <a href="/docs/r/">R</a>, <a href="https://github.com/apache/arrow/blob/main/ruby/README.md">Ruby</a>, and <a href="https://docs.rs/crate/arrow/">Rust</a>. |
