ShardMasterRegexp

Identify the node to be configured as sharded cluster data node 1 based on hostname.

Synopsis

[Startup]    ShardMasterRegexp=regular_expression

Description

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.
