If necessary, you can access a specific shard by connecting to it using the shard-specific database name, or issuing a USE statement to switch to it if already connected to vtgate.

For a keyspace ks and shard -80, you would use the database name ks:-80. This is called manual shard targeting. Please note that shard targeting is considered an advanced feature and should be used with caution. In particular, it is possible to insert rows into the wrong shard by using shard targeting.
