            <title>[SERVER-54614] Introduce striped lock to BucketCatalog to improve throughput</title>
                <link>https://jira.mongodb.org/browse/SERVER-54614</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;In many-writer, large-batch timeseries workloads, a great deal of time is spent waiting on the mutex while we do read-only operations on shared data structures. We can introduced a striped (i.e. sharded, partitioned) mutex to support this in a way that allows multiple concurrent readers, but still allows an operation to take an exclusive lock (by locking all stripes) to perform a write.&lt;/p&gt;</description>
