            <title>[SERVER-65337] Tenant migration, split, and merge POS&apos;s should default their thread pools to 0 threads</title>
                <link>https://jira.mongodb.org/browse/SERVER-65337</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;Currently the TenantMigrationDonorService&apos;s thread pool&#160;&lt;a href=&quot;https://github.com/mongodb/mongo/blob/65656c587aeb384c173be1b84d0b3057563417f4/src/mongo/db/repl/tenant_migration_donor_service.h#L60&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;uses&lt;/a&gt; the &lt;a href=&quot;https://github.com/mongodb/mongo/blob/156a1456c05956125658a90382271d596a10368d/src/mongo/util/concurrency/thread_pool.h#L57&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;ThreadPool::Limits::minThreads default, which is 1&lt;/a&gt;.&lt;/p&gt;

&lt;p&gt;It should instead set the minThreads to 0, similar to how it sets maxThreads to repl::maxTenantMigrationDonorServiceThreadPoolSize.&lt;/p&gt;

&lt;p&gt;We should update TenantMigrationDonorService, as well as check and update TenantMigrationRecipientService and the split service if needed.&lt;/p&gt;</description>
