            <title>[SERVER-46201] Implement a generic ReplicaSetStateAwareService</title>
                <link>https://jira.mongodb.org/browse/SERVER-46201</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;Currently there is a lot of duplication of code to initialise and change the state of internal services as the state of replication changes. Just a few examples of this are the &lt;a href=&quot;https://github.com/mongodb/mongo/blob/44a107ad428459cad6260490ae98bca442e07385/src/mongo/db/repl/replication_coordinator_external_state_impl.cpp#L719&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;&lt;tt&gt;ShardServerCatalogCacheLoader&lt;/tt&gt;&lt;/a&gt;, &lt;a href=&quot;https://github.com/mongodb/mongo/blob/44a107ad428459cad6260490ae98bca442e07385/src/mongo/db/repl/replication_coordinator_external_state_impl.cpp#L758&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;&lt;tt&gt;ClusterIdentityLoader&lt;/tt&gt;&lt;/a&gt; and the &lt;a href=&quot;https://github.com/mongodb/mongo/blob/44a107ad428459cad6260490ae98bca442e07385/src/mongo/db/repl/replication_coordinator_external_state_impl.cpp#L460&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;&lt;tt&gt;Balancer&lt;/tt&gt;&lt;/a&gt;.&lt;/p&gt;

&lt;p&gt;Instead of having everything in the &lt;tt&gt;ReplicationCoordinatorExternalState&lt;/tt&gt;, this ticket proposes to have a global registry of replication-aware services (where global means for a single MongoD process), on which developers can register their service implementations. The service implementations will override a strict set of virtual functions corresponding to the state transitions of the replica set. These state transitions will have pre-defined rules of what locks are held, what can be done under them (for example no blocking I/O during step-down), etc.&lt;/p&gt;

&lt;p&gt;The interface of the registry should be similar to &lt;a href=&quot;https://github.com/mongodb/mongo/blob/44a107ad428459cad6260490ae98bca442e07385/src/mongo/db/s/collection_sharding_state_factory_embedded.cpp#L104&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;&lt;tt&gt;ServiceContext::ConstructorActionRegisterer&lt;/tt&gt;&lt;/a&gt; so that services are automatically registered as the node starts-up.&lt;/p&gt;

&lt;p&gt;As part of this ticket, at least one service (perhaps the Sharding Balancer) should be converted to use this framework.&lt;/p&gt;</description>
