Options

Table 2-64 GDSCTL modify shardgroup Options

Option	Description
-shardgroup shardgroup_name	Specify the name of the shardgroup to be modified.
-region region_name	Specify the region the shardgroup resides in.
-shardspace shardspace_name	Specify the shardspace this shardgroup belongs to.
-repfactor number	Specify the number of replicas for each piece of data stored in this shardgroup.
-deploy_as {PRIMARY | STANDBY | ACTIVE_STANDBY}	Specify the initial role for a newly deployed database: PRIMARY, STANDBY, or ACTIVE_STANDBY.

Usage Notes

All shardgroup attributes, except for DEPLOY_AS, can only be modified when the shardgroup does not contain any deployed shards. DEPLOY_AS can be modified at any time because it does not affect shards that were already added to the shardgroup.

Examples

Modify the GROUP1 shardgroup to have a replication factor of 3.
