ApsaraDB for MongoDB - Supports Batch Parallel Creation of Mongos and Shard Nodes for Sharded Cluster Instances
If you require a large number of mongos or shard nodes in you sharded cluster but a relatively small number of mongos or shard nodes are created when you create the instance, you must add them in sequence before this feature is available. The waiting time is relatively long. ApsaraDB for MongoDB supports batch parallel creation of mongos and shard nodes for sharded cluster instances. This can reduce the waiting time of O&M engineers or DBAs from hours to minutes and improve operation efficiency and user experience.
