Start or continue replicating a database from a remote host to a local database.

Syntax

REPLICATE DATABASE db_name FROM master_user[:'master_password']@master_host[:master_port][/master_db_name]

Remarks

• db_name is the name of the target database on the secondary MemSQL instance. REPLICATE DATABASE will always attempt to create a new database named db_name. The database name on the secondary does not need to match the name of its corresponding remote primary database.
• master_user and master_password must grant access to the primary database. The password is assumed to be blank if master_password is not specified explicitly. If you specify a password, enclose it in single quotes.
• master_host is the host name or IPv4/IPv6 pointing to the remote database. It can be quoted to allow special characters (e.g. “-", among others).
• master_db_name is the name of the remote, primary database. If it is not specified explicitly, MemSQL attempts to replicate from db_name on the master MemSQL instance.
• While replicating, the database is in the replicating state (see Database States).
• The long form of CONTINUE REPLICATING can be used to re-point a replica from one master to another.

Examples

Basic Usage
