Start or continue replicating a database from a remote host to a local database.
REPLICATE DATABASE db_name FROM master_user[:'master_password']@master_host[:master_port][/master_db_name]
db_nameis the name of the target database on the secondary MemSQL instance.
REPLICATE DATABASEwill 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_passwordmust grant access to the primary database. The password is assumed to be blank if
master_passwordis not specified explicitly. If you specify a password, enclose it in single quotes.
master_hostis 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_nameis the name of the remote, primary database. If it is not specified explicitly, MemSQL attempts to replicate from
db_nameon the master MemSQL instance.
- While replicating, the database is in the
replicatingstate (see Database States).
- The long form of
CONTINUE REPLICATINGcan be used to re-point a replica from one master to another.
