            <title>[DOCS-13526] Investigate changes in SERVER-38731: Ability to specify sync source read preference in initial sync</title>
                <link>https://jira.mongodb.org/browse/DOCS-13526</link>
                <project id="10380" key="DOCS">Documentation</project>
                    <description>&lt;h2&gt;&lt;a name=&quot;Description&quot;&gt;&lt;/a&gt;Description&lt;/h2&gt;

    &lt;div class=&quot;panel&quot; style=&quot;background-color: #c2d2c2;border-width: 1px;&quot;&gt;&lt;div class=&quot;panelHeader&quot; style=&quot;border-bottom-width: 1px;background-color: #239eb0;&quot;&gt;&lt;b&gt;Downstream Change Summary&lt;/b&gt;&lt;/div&gt;&lt;div class=&quot;panelContent&quot; style=&quot;background-color: #c2d2c2;&quot;&gt;
&lt;p&gt;    Adds parameter initialSyncSourceReadPreference; see Initial Sync Semantics documentation.&lt;/p&gt;
&lt;/div&gt;&lt;/div&gt;
&lt;h2&gt;&lt;a name=&quot;DescriptionofLinkedTicket&quot;&gt;&lt;/a&gt;Description of Linked Ticket&lt;/h2&gt;
&lt;p&gt;    Our current implementation of choosing a sync source for initial sync as well as steady state sync could be improved to include preferences provided by the user for situations including:&lt;/p&gt;
&lt;ul&gt;
	&lt;li&gt;not wanting to sync from the primary to mitigate impact to production applications that are targeting the primary&lt;/li&gt;
	&lt;li&gt;preference to sync from a node on the same LAN vs having multiple nodes make the trip across the WAN (even if ping times would dictate otherwise)&lt;/li&gt;
	&lt;li&gt;syncing from a specific node based on specific user preference&lt;/li&gt;
&lt;/ul&gt;


&lt;p&gt;If the preference is not specified or can not be accommodated then we should fall back to choosing based on latency and currency as we do today.&#160;&#160;&lt;/p&gt;

&lt;p&gt;It would be helpful for the specification of a sync source preference to be part of the replica set configuration so it is easily noticed and easily managed.&#160; The log should reflect the preference and the reason it was overridden when need be.&lt;/p&gt;


&lt;h2&gt;&lt;a name=&quot;Scopeofchanges&quot;&gt;&lt;/a&gt;Scope of changes&lt;/h2&gt;

&lt;h2&gt;&lt;a name=&quot;ImpacttoOtherDocs&quot;&gt;&lt;/a&gt;Impact to Other Docs&lt;/h2&gt;

&lt;h2&gt;&lt;a name=&quot;MVP%28WorkandDate%29&quot;&gt;&lt;/a&gt;MVP (Work and Date)&lt;/h2&gt;

&lt;h2&gt;&lt;a name=&quot;Resources%28ScopeorDesignDocs%2CInvision%2Cetc.%29&quot;&gt;&lt;/a&gt;Resources (Scope or Design Docs, Invision, etc.)&lt;/h2&gt;
