You use a read replica to offload work from a Cloud SQL instance. Because of these benefits, you can't disable GTID-based replication in Cloud SQL. There are fewer errors with replicas and with point-in-time recovery. A GTID uses absolute coordinates so the replica of a Cloud SQL instance can point to its primary instance, and you don't have to specify a file name for the binary log or a position in the CHANGE MASTER statement. Because each transaction has a unique identifier, the MySQL server can keep track of the transactions that it has run. GTIDs uniquely identify each transaction on the server and within a replication setup. However, Cloud SQL supports global transaction identifier (GTID)-based replication. You can also use Database Migration Serviceįor continuous replication from a source database server to Cloud SQL.Ĭloud SQL doesn't support replication between two external servers. New customers get 300 in free credits to spend on Cloud SQL for MySQL. With Cloud SQL for MySQL, you can spend less time on your database operations and more time on your applications. Cloud SQL replicas, when replicating from an external server MySQL is the world's most popular open source relational database.You can also promote a replica to replace anĬloud SQL supports the following types of replicas: This way, you can use it in place of an instance that's in a In a disaster recovery scenario, you can promote a replica to convert it to a Instance that represents the source database server in Cloud SQL called The copies that reside inĬloud SQL are called Cloud SQL replicas. Is replicated is the source database server. When referring to an on-premises database, the replication scenario is called The primary instance and read replicas reside in When referring to a Cloud SQL instance, the instance that is replicated isĬalled the primary instance and the copies are called Migrating data from an on-premises database to Cloud SQLĪdditionally, a replica could be promoted if the original instance.The primary reason for using replication is to scale the use of data in a On-premises database, and offload work to the copies. Replication is the ability to create copies of a Cloud SQL instance or an Save money with our transparent approach to pricing Migrate from PaaS: Cloud Foundry, OpenshiftĬOVID-19 Solutions for the Healthcare Industry Horizontally Scale a MySQL Database Backend with Cloud SQL and ProxySQL.
