Creating a Shard Catalog for Directory-Based Sharding

Directory-based sharding is an enhancement of the User-defined sharding method, so the shard catalog is configured with the user-defined sharding option.

GDSCTL> create shardcatalog -database catalog_connect_string
 -user mysdbadmin/mysdbadmin_password -sharding user
 -protectmode maxperformance

More details about creating a shard catalog, including specifying the shard catalog Connect String and connecting to the shard catalog can be found in Create the Shard Catalog.
