Collection::isCapped does appear to check in-memory state, unlike checking for temp, but checking at write time would add two additional checks &amp;#8211; one for isShard, one for isCapped &amp;#8211; to the write path.&lt;/p&gt;</comment>

Replica sets that aren&apos;t shard-servers will still be allowed to touch capped collections.&lt;/p&gt;</comment>
                            <comment id="2198324" author="judah.schvimer" created="Mon, 1 Apr 2019 20:32:15 +0000"  >&lt;p&gt;If &lt;a href=&quot;https://jira.mongodb.org/secure/ViewProfile.jspa?name=alyson.cabral&quot; class=&quot;user-hover&quot; rel=&quot;alyson.cabral&quot;&gt;alyson.cabral&lt;/a&gt; is ok with it, we&apos;ll make the behavior: mongos does nothing, mongod returns an &lt;tt&gt;OperationNotSupportedInTransaction&lt;/tt&gt; error when a statement touches a capped collection, the transaction may implicitly be aborted by the replica set depending on if the implementation requires it. This prohibition will apply to shardservers and replica sets that are not part of a sharded cluster alike. This will make it a slight behavior change from 4.0 single replica set transactions which did allow transactions to touch capped collections.&lt;/p&gt;</comment>
                            <comment id="2198313" author="kaloian.manassiev" created="Mon, 1 Apr 2019 20:22:14 +0000"  >&lt;p&gt;It is correct that with 2PC commit optimizations a transaction might not become 2PC until after it has accessed a capped collection (or a collection has become capped).&lt;/p&gt;

&lt;p&gt;I am fine with disabling transactions on capped collections and would rather do it not just for sharding, but for replica sets as well.&lt;/p&gt;</comment>
                            <comment id="2198021" author="schwerin" created="Mon, 1 Apr 2019 17:44:01 +0000"  >&lt;p&gt;I think it makes sense to fail transactions that touch capped collections. I&apos;d be willing to do it universally, since as Geert points out, the sequential ordering requirement on capped collections makes using them with transactions hazardous. I&apos;d also be willing to just do it in all transactions on sharded clusters &amp;#8211; if a shard server detects a transaction accessing a capped collection, it could abort the transaction immediately. Not really worth waiting to see if it might become two-phase, and it&apos;s not detectable &lt;em&gt;a priori&lt;/em&gt;. You sometimes don&apos;t know until commit, or at least until the second write, and that seems like a bad place to report the error.&lt;/p&gt;</comment>
                            <comment id="2197822" author="judah.schvimer" created="Mon, 1 Apr 2019 15:37:25 +0000"  >&lt;p&gt;&lt;a href=&quot;https://jira.mongodb.org/secure/ViewProfile.jspa?name=kaloian.manassiev&quot; class=&quot;user-hover&quot; rel=&quot;kaloian.manassiev&quot;&gt;kaloian.manassiev&lt;/a&gt;, would the above be possible?&lt;/p&gt;

&lt;p&gt;We could alternatively fail any mongodb transaction that tried to touch a capped collection as soon as it attempted to do so, not just cross-shard ones. We could also do this only for single replica set transactions on shardservers to leave non sharded behavior unchanged. If we only want to prevent cross-shard transactions touching capped collections we cannot do that until prepare time on mongod (though could potentially on mongos earlier).&lt;/p&gt;</comment>
                            <comment id="2197747" author="alyson.cabral" created="Mon, 1 Apr 2019 15:02:43 +0000"  >&lt;p&gt;Yes, this is ok behavior. Is it possible to make this even more obvious to end users by not allowing them to start a transaction on a capped collection through a mongos? I try to avoid things that could work in dev and break as soon as someone pushes to production, just due to the placement of chunks. I prefer stricter failing if it is ultimately more obvious to catch. &lt;/p&gt;

                            <comment id="2195812" author="judah.schvimer" created="Fri, 29 Mar 2019 13:14:30 +0000"  >&lt;p&gt;This lock yielding was added in &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-37199&quot; title=&quot;Yield locks of transactions in secondary application&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-37199&quot;&gt;&lt;del&gt;SERVER-37199&lt;/del&gt;&lt;/a&gt; to release locks on stepdown and reacquire them on stepup. We could investigate if relaxing  the invariant for that specific lock restore is safe. Concurrent writers are prevented by secondary oplog application concurrency control. Concurrent readers would be possible, but that may be safe. &lt;/p&gt;

&lt;blockquote&gt;
&lt;p&gt;a prepared transaction that succeeds on one node may not succeed on another node, however a prepared transaction may not be aborted.&lt;/p&gt;&lt;/blockquote&gt;
&lt;p&gt;&lt;a href=&quot;https://jira.mongodb.org/secure/ViewProfile.jspa?name=geert.bosch&quot; class=&quot;user-hover&quot; rel=&quot;geert.bosch&quot;&gt;geert.bosch&lt;/a&gt;&apos;s third point makes it clear to me though that the above invariant relaxation won&apos;t be sufficient with the guarantees prepared transactions expect to provide.&lt;/p&gt;

&lt;p&gt;I think banning capped collections in prepared transactions similarly to &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-38139&quot; title=&quot;Ban temporary collections in prepared transactions&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-38139&quot;&gt;&lt;del&gt;SERVER-38139&lt;/del&gt;&lt;/a&gt; for temp collections makes sense. I think &lt;a href=&quot;https://jira.mongodb.org/secure/ViewProfile.jspa?name=schwerin&quot; class=&quot;user-hover&quot; rel=&quot;schwerin&quot;&gt;schwerin&lt;/a&gt; is on board with this given offline discussion. &lt;a href=&quot;https://jira.mongodb.org/secure/ViewProfile.jspa?name=alyson.cabral&quot; class=&quot;user-hover&quot; rel=&quot;alyson.cabral&quot;&gt;alyson.cabral&lt;/a&gt;, is this acceptable behavior?&lt;/p&gt;</comment>
                            <comment id="2195344" author="geert.bosch" created="Thu, 28 Mar 2019 22:08:50 +0000"  >&lt;p&gt;I think that cross-shard transactions involving capped collections (other than the oplog) is problematic. There are few reasons:&lt;/p&gt;
&lt;ul&gt;
	&lt;li&gt;Capped collections enforce sequential insert order. As a result only single operation may be in progress at a time. Currently we use &lt;tt&gt;MODE_X&lt;/tt&gt; locks to enforce the ordering, but prepared transactions do not allow such locks.&lt;/li&gt;
	&lt;li&gt;Prepared transactions must be able to survive replica-set state transitions, but in absence of locking, there is no good way to enforce ordering.&lt;/li&gt;
	&lt;li&gt;Operations on capped collections may implicitly remove documents from a collection, but whether that happens or not may differ between replica-set members. So, a prepared transaction that succeeds on one node may not succeed on another node, however a prepared transaction may not be aborted.&lt;/li&gt;
&lt;/ul&gt;


&lt;p&gt;Without a significant redesign of capped collections, we cannot support cross-shard operations on them. I think any effort to make them somewhat work should instead be spent on a workable replacement in the form of improvements to TTL collections.&lt;/p&gt;

&lt;p&gt;We should just add an extra check at prepare time to not allow capped collections.&lt;/p&gt;</comment>
