            <title>[JAVA-5186] Change server pinning implementation to not rely on Cluster#getDescription</title>
                <link>https://jira.mongodb.org/browse/JAVA-5186</link>
                <project id="10006" key="JAVA">Java Driver</project>
                    <description>&lt;p&gt;The current implementation of server address pinning for transactions on sharded and load-balanced clusters relies on the &lt;tt&gt;Cluster#getDescription&lt;/tt&gt; method.  This means that blocking has to be done twice instead of just once via &lt;tt&gt;Cluster#selectServer&lt;/tt&gt;.  It would be easy to refactor so that the cluster type (which is all that is needed) is derived instead from the &lt;tt&gt;ConnectionSource&lt;/tt&gt; after it&apos;s selected.&lt;/p&gt;

&lt;p&gt;This would simplify the code, allow the removal of &lt;tt&gt;Cluster#getDescription&lt;/tt&gt;, and make server selection timeout logging and exception message more consistent.&lt;/p&gt;</description>

&lt;p&gt;Message: Refactor transaction server pinning (#1211)&lt;/p&gt;

&lt;ul&gt;
	&lt;li&gt;Determine whether TransactionContext is required based on ConnectionSource&apos;s ServerDescription&lt;br/&gt;
instead of the ClusterDescription&lt;/li&gt;
	&lt;li&gt;Remove Cluster#getDescription and update tests that relied on it&lt;/li&gt;
&lt;/ul&gt;
