| <p>The filesystem interface exposes a simplified view of the underlying data |

| <code class="xref cpp cpp-class docutils literal notranslate"><span class="pre">metadata</span></code> about file entries, such as the file size |

| <p>Filesystem instances can be constructed from URI strings using one of the |

| <p>If a filesystem implementation requires initialization before any instances |
| may be constructed, this should be included in the corresponding factory or |
| otherwise automatically ensured before the factory is invoked. Likewise if |
| a filesystem implementation requires tear down before the process ends, this |
| can be wrapped in a function and registered alongside the factory. All |
| finalizers will be called by <a class="reference internal" href="api/filesystem.html#_CPPv4N5arrow2fs15EnsureFinalizedEv" title="arrow::fs::EnsureFinalized"><code class="xref cpp cpp-func docutils literal notranslate"><span class="pre">EnsureFinalized()</span></code></a>.</p> |
| <p>Build complexity can be decreased by compartmentalizing a filesystem |
| implementation into a separate shared library, which applications may |
| link or load dynamically. Arrow’s built-in filesystem implementations |
| also follow this pattern. If a shared library containing instances of |
| <a class="reference internal" href="api/filesystem.html#_CPPv4N5arrow2fs19FileSystemRegistrarE" title="arrow::fs::FileSystemRegistrar"><code class="xref cpp cpp-class docutils literal notranslate"><span class="pre">FileSystemRegistrar</span></code></a> must be dynamically loaded, |
| <code class="xref cpp cpp-func docutils literal notranslate"><span class="pre">LoadFileSystemFactories()</span></code> should be used to load it. |
| If such a library might link statically to arrow, it |
| should have exactly one of its sources |
| <code class="docutils literal notranslate"><span class="pre">#include</span> <span class="pre">"arrow/filesystem/filesystem_library.h"</span></code> |
| in order to ensure the presence of the symbol on which |
| <code class="xref cpp cpp-func docutils literal notranslate"><span class="pre">LoadFileSystemFactories()</span></code> depends.</p> |
