            <title>[SERVER-53717] Dynamically split large concurrency tasks</title>
                <link>https://jira.mongodb.org/browse/SERVER-53717</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;There are several concurrency tasks that have long-running times. We should be able to dynamically split these to bring the wall-clock time down.&lt;/p&gt;

&lt;p&gt;Also, these require running on large distros to avoid OOM, but new build variants are being added that don&apos;t run them on the right distros. By splitting them dynamically, we can handle that without new build variants needing to know.&lt;/p&gt;

&lt;p&gt;The tasks we will split:&lt;/p&gt;
&lt;ul&gt;
	&lt;li&gt;concurrency_replication_causal_consistency&lt;/li&gt;
	&lt;li&gt;concurrency_sharded_causal_consistency_and_balancer&lt;/li&gt;
	&lt;li&gt;concurrency_sharded_clusterwide_ops_add_remove_shards&lt;/li&gt;
	&lt;li&gt;concurrency_sharded_local_read_write_multi_stmt_txn&lt;/li&gt;
	&lt;li&gt;concurrency_sharded_local_read_write_multi_stmt_txn_with_balancer&lt;/li&gt;
	&lt;li&gt;concurrency_sharded_multi_stmt_txn&lt;/li&gt;
	&lt;li&gt;concurrency_sharded_multi_stmt_txn_with_balancer&lt;/li&gt;
	&lt;li&gt;concurrency_sharded_multi_stmt_txn_with_stepdowns&lt;/li&gt;
	&lt;li&gt;concurrency_sharded_replication&lt;/li&gt;
	&lt;li&gt;concurrency_sharded_replication_no_txns&lt;/li&gt;
	&lt;li&gt;concurrency_sharded_replication_no_txns_with_balancer&lt;/li&gt;
	&lt;li&gt;concurrency_sharded_replication_with_balancer&lt;/li&gt;
	&lt;li&gt;concurrency_sharded_with_stepdowns&lt;/li&gt;
	&lt;li&gt;concurrency_sharded_with_stepdowns_and_balancer&lt;/li&gt;
&lt;/ul&gt;
