<h2 id="introduction">Introduction</h2>
<p>Apache ShardingSphere uses ThreadLocal to manage sharding key value or hint route.
Users can add sharding values to HintManager, and those values only take effect within the current thread.</p>
<p>Usage of hint:</p>
<ul>
<li>Sharding columns are not in SQL and table definition, but in external business logic.</li>
<li>Some operations forced to do in the primary database.</li>
</ul>
<h2 id="usage">Usage</h2>
<h3 id="sharding-with-hint">Sharding with Hint</h3>
<h4 id="hint-configuration">Hint Configuration</h4>
<p>Hint algorithms require users to implement the interface of <code>org.apache.shardingsphere.api.sharding.hint.HintShardingAlgorithm</code>.
Apache ShardingSphere will acquire sharding values from HintManager to route.</p>
<p>Take the following configurations for reference:</p>

<ul>
<li>Use <code>hintManager.addDatabaseShardingValue</code> to add sharding key value of data source.</li>
<li>Use <code>hintManager.addTableShardingValue</code> to add sharding key value of table.</li>
</ul>
<blockquote>
<p>Users can use <code>hintManager.setDatabaseShardingValue</code> to add sharding in hint route to some certain sharding database without sharding tables.
After that, SQL parse and rewrite phase will be skipped and the overall enforcement efficiency can be enhanced.</p>
</blockquote>
<h4 id="clean-hint-values">Clean Hint Values</h4>
<p>Sharding values are saved in <code>ThreadLocal</code>, so it is necessary to use <code>hintManager.close()</code> to clean <code>ThreadLocal</code>.</p>
<p><strong><code>HintManager</code> has implemented <code>AutoCloseable</code>. We recommend to close it automatically with <code>try with resource</code>.</strong></p>
