<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="{{ site.baseurl }}/overview/">Learn more</a> about the design or
        <a href="{{ site.baseurl }}/docs/format/Columnar.html">read the specification</a>.</p>

      <h3>Libraries</h3>
      <p>Arrow's libraries implement the format and provide building blocks for a range of <a href="{{ site.baseurl }}/use_cases/">use cases</a>, including high performance analytics. <a href="{{ site.baseurl }}/powered_by/">Many popular projects</a> use Arrow to ship columnar data efficiently or as the basis for analytic engines.</p>
