Migrate Google Cloud SQL for PostgreSQL to Amazon RDS and Amazon Aurora using pglogical
- PostgreSQL is a popular open-source relational database for many developers and can be easily deployed on AWS with services like Amazon RDS and Aurora PostgreSQL-Compatible Edition.
- Migrating a PostgreSQL database from Google Cloud SQL to Amazon RDS or Aurora can be accomplished using the pglogical extension for logical replication.
- The pglogical extension replicates data changes efficiently and is resilient to network faults, functioning with both RDS for PostgreSQL and Aurora PostgreSQL.
- Steps involve setting up the primary Cloud SQL instance, configuring logical replication with pglogical extension, and creating provider and subscriber nodes.
- Limitations of pglogical include the need for workarounds for sequences, primary key changes, extensions, materialized views, and DDLs during migration.
- The setup allows for replicating lower PostgreSQL versions to higher ones and the authors provide expertise in database migration and optimization.
- The use of surrogate keys, manual extension replication, and considerations for schema changes and large objects are discussed to address limitations in replication.
- The post provides detailed steps, commands, and precautions for a successful migration from Google Cloud to AWS RDS or Aurora PostgreSQL.
- Authors include Sarabjeet Singh, Kranthi Kiran Burada, and Jerome Darko, who specialize in database solutions and migrations at AWS.
