            <title>[SERVER-36638] Replace state machine commit coordination implementation with Futures implementation</title>
                <link>https://jira.mongodb.org/browse/SERVER-36638</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;There are three improvements we could make to how the coordinator shard processes votes and sends commit/abort:&lt;/p&gt;

&lt;p&gt;1) Use one of the Grid&apos;s &quot;arbitrary executors&quot; rather than the Grid&apos;s &quot;fixed executor&quot;. Currently, the fixed executor is used because it is the only executor for which the a mock network is supported by the sharding unit test fixtures.&lt;/p&gt;

&lt;p&gt;2) If a voteCommit or voteAbort triggers making the decision, do not block the voteCommit/voteAbort Client thread on things like persisting the decision, waiting for majority writeConcern, sending the decision and waiting for acks.&lt;/p&gt;

&lt;p&gt;3) Make sending an abort decision a &quot;fire and forget&quot; message. Currently, the ARS does not support sending &quot;fire and forget&quot; messages.&lt;/p&gt;</description>
