shardCount

The number of data shards. This parameter is available only if you create a cluster instance that uses cloud disks. You can use this parameter to specify a custom number of data shards.

NOTE: The start time to the end time must be 1 hour. For example, the MaintainStartTime is 01:00Z, then the MaintainEndTime must be 02:00Z. NOTE: You must specify at least one of the capacity and instance_class parameters when you call create instance operation. NOTE: The private_ip must be in the Classless Inter-Domain Routing (CIDR) block of the VSwitch to which the instance belongs. NOTE: If you specify the srcdb_instance_id parameter, you must specify the backup_id or restore_time parameter.
