            <title>[SERVER-38444] Coordinating a transaction should run fully in the ThreadPoolTaskExecutor for sharding tasks</title>
                <link>https://jira.mongodb.org/browse/SERVER-38444</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;Currently, coordinating a transaction &quot;hops&quot; between the TransactionCoordinatorService&apos;s ThreadPool and the fixed ThreadPoolTaskExecutor on the Grid.&lt;/p&gt;

&lt;p&gt;It does so in order to run the parts of the commit coordination that block on the local storage engine in a separate thread pool from the Grid&apos;s fixed ThreadPoolTaskExecutor.&lt;/p&gt;

&lt;p&gt;This ticket is to make coordinating the transaction run wholly on the fixed ThreadPoolTaskExecutor on the Grid, and set the size of the thread pool in that ThreadPoolTaskExecutor to unbounded.&lt;/p&gt;</description>

We&apos;ll ramp up the max number of threads on the TaskExecutor to be essentially infinite.&lt;/p&gt;</comment>
