            <title>[DOCS-14167] Investigate changes in SERVER-53394: Make ShardingTaskExecutorPoolReplicaSetMatching default to disabled for MongoD</title>
                <link>https://jira.mongodb.org/browse/DOCS-14167</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;    Downstream changes:&lt;br/&gt;
Configuration Changes (Atlas, STAR, docs)&lt;br/&gt;
The ShardingTaskExecutorPoolReplicaSetMatching server parameter (see &lt;a href=&quot;https://docs.mongodb.com/manual/reference/parameters/#param.ShardingTaskExecutorPoolReplicaSetMatching&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;https://docs.mongodb.com/manual/reference/parameters/#param.ShardingTaskExecutorPoolReplicaSetMatching&lt;/a&gt;) has a new possible value, &quot;automatic&quot;. This new value is now the default. The behavior of this new value depends on the process: on mongos, it is identical to the existing &quot;matchPrimaryNode&quot; option; on mongod, it is identical to the existing &quot;disabled&quot; option. (On mongos, this parameter determines the minimum size limit of the mongos instance&apos;s connection pools to the secondaries of the cluster&apos;s shards; on mongod, this parameter determines the minimum size limit of the mongod instance&apos;s connection pools to the secondaries of &lt;em&gt;other&lt;/em&gt; shards in the cluster.)&lt;/p&gt;

&lt;p&gt;Command results changes (ADL, drivers, BIC, docs):&lt;br/&gt;
The connPoolStats command output now contains an additional field, &quot;replicaSetMatchingStrategy&quot;; the value of this field describes the actual policy used by that process to determine the min size of connection pools from that server to RS secondaries in (other) shards. The policy will either be &quot;matchPrimaryNode&quot;, &quot;matchBusiestNode&quot;, or &quot;disabled&quot;, with the behavior described by the existing docs for the STEPRSM parameter. Note that even if the &quot;automatic&quot; value is used to set the server parameter, the &quot;replicaSetMatchingStrategy&quot; field in the connPoolStats output will describe the &lt;em&gt;actual&lt;/em&gt; policy being used, not &quot;automatic.&quot; This contrasts with the output of using getParameter() to find the value of the STEPRSM parameter, which will display &quot;automatic&quot; if that is the value of the server parameter.&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;    We currently set ShardingTaskExecutorPoolReplicaSetMatching to &quot;matchPrimaryNode&quot; by default for both MongoD and MongoS (see &lt;a href=&quot;https://github.com/mongodb/mongo/blob/04401a326046babcb390cc444f52699f732b3b2f/src/mongo/s/sharding_task_executor_pool.idl#L87-L93&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;here&lt;/a&gt;). However, the &quot;matchPrimaryNode&quot; behavior can be problematic for topologies when multiple shardsvrs experience a rapid influx of cross-shard operations. We should disable this behavior on MongoD nodes but not MongoS nodes.&lt;/p&gt;
