When the ShardRole parameter is set to AUTO, ShardRegexp validates that the name of the instance’s host matches the regular expression provided; instances on hosts that do not match are not configured as cluster members. In conjunction with several other parameters, ShardRegexp 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 node to be configured as sharded cluster data node 1 based on hostname.
ShardRegexp to identify the nodes to be configured as sharded cluster data nodes (other than data node 1) based on hostname.
