| <h1>Apache Arrow Java Cookbook<a class="headerlink" href="#apache-arrow-java-cookbook" title="Link to this heading">¶</a></h1> |
| <p>The Apache Arrow Cookbook is a collection of recipes which demonstrate how to solve many common tasks that users might need to perform when working with Arrow data. The examples in this cookbook will also serve as robust and well performing solutions to those tasks.</p> |
| <p>To get started with Apache Arrow in Java, see the |
| <a class="reference external" href="https://arrow.apache.org/docs/java/install.html">Installation Instructions</a>.</p> |
| <p>This cookbook is tested with Apache Arrow 14.0.0.</p> |
