            <title>[SERVER-20211] Cross collection batch operation</title>
                <link>https://jira.mongodb.org/browse/SERVER-20211</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;It may be useful to allow bulk operations to span collections. I have found that bulk operations tend to be significantly more performant (than multiple discreet operations). In my workflow I have come across several scenarios which would benefit from this feature.&lt;/p&gt;

&lt;p&gt;For example, upon completion of a certain program operation, I need to update one table and insert a summary document in another. These two operations are always tied together but it doesn&apos;t make sense for them to be within the same collection.&lt;/p&gt;

&lt;p&gt;By extension, being able to batch multiple operations across multiple databases would also be useful in my workload. In my case I have 1 insertion thread per collection (and can have many hundreds of threads per collections). A cross-database batch operation may allow me to use a small thread pool to perform the same operation in a more efficient manner.&lt;/p&gt;</description>
