            <title>[DOCS-11716] Docs for SERVER-33244: Make all lock acquisitions for transactions have 0 second timeout</title>
                <link>https://jira.mongodb.org/browse/DOCS-11716</link>
                <project id="10380" key="DOCS">Documentation</project>
                    <description>&lt;h2&gt;&lt;a name=&quot;Description%3A&quot;&gt;&lt;/a&gt;Description: &lt;/h2&gt;

&lt;p&gt;New server parameter, maxTransactionLockRequestTimeoutMillis. Start up parameter and settable via setParameter, gettable via getParameter.&lt;/p&gt;

&lt;p&gt;Server parameter that dictates the max number of milliseconds that any transaction lock request will wait for lock acquisition. If an operation provides a greater timeout in a lock request, maxTransactionLockRequestTimeoutMillis will override it. If this is set to a negative value, it is inactive and nothing will be overridden. &amp;#8211; should probably message this as set maxTransactionLockRequestTimeoutMillis to -1 to unset the override, and forget about the rest of the allowable negative values.&lt;/p&gt;

&lt;p&gt;The default of 0 milliseconds will ensure that transaction operations will immediately give up trying to take any lock if it is not immediately available. This prevents deadlocks between transactions. Setting a non-zero, positive value will also help obviate deadlocks, but won&apos;t abort a potentially deadlocked transaction operation for however long has been set.&lt;/p&gt;

&lt;h2&gt;&lt;a name=&quot;Scopeofchanges%3A&quot;&gt;&lt;/a&gt;Scope of changes: &lt;/h2&gt;

&lt;ul&gt;
	&lt;li&gt;4.0.txt&lt;/li&gt;
	&lt;li&gt;transactions&lt;/li&gt;
	&lt;li&gt;parameters&lt;/li&gt;
&lt;/ul&gt;

&lt;h2&gt;&lt;a name=&quot;MVP%3A&quot;&gt;&lt;/a&gt;MVP: &lt;/h2&gt;

&lt;h2&gt;&lt;a name=&quot;Resources%3A&quot;&gt;&lt;/a&gt;Resources: &lt;/h2&gt;

&lt;h2&gt;&lt;a name=&quot;EngineeringTicketDescription%3A&quot;&gt;&lt;/a&gt;Engineering Ticket Description:&lt;/h2&gt;

&lt;p&gt;Txns should do no waiting for locks, they should fail the lock acquisition immediately if there&apos;s any conflict.  They should also abort the transaction if that happens.&lt;/p&gt;</description>
