When the ShardRole parameter is set to AUTO, ShardMasterRegexp identifies the instance to be configured as data node 1 if the name of the instance’s host matches the regular expression specified as its value. In conjunction with several other parameters, ShardMasterRegexp can be used to deploy a sharded cluster. For a description of this process, see Configure or Deploy a Mirrored Cluster Using CPF Settings in the “Horizontally Scaling for Data Volume with Sharding” chapter in the Scalability Guide.
ArbiterURL to specify the address of the arbiter for a mirrored sharded cluster.
ShardRole to specify the sharded cluster role of the instance.
ShardClusterURL to specify the node to use as a template when adding an instance to a sharded cluster.
ShardMirrorMember to specify the failover role of a data node in a mirrored sharded cluster.
ShardMasterRegexp to identify the sharded cluster node to be configured as data node 1 based on hostname.
