Amazon Aurora PostgreSQL Supports pglogical Extension
Starting today, Amazon Aurora PostgreSQL supports the pglogical extension. pglogical is an open source PostgreSQL extension that helps customers replicate data between independent Aurora PostgreSQL databases while maintaining consistent read-write access and a mix of private and common data in each database. Amazon Aurora pglogical uses logical replication to copy data changes between independent Aurora PostgreSQL databases, optionally resolving conflicts based on standard algorithms. Customers can enable pglogical from within their Aurora PostgreSQL instances, and pay only for the additional clusters and cross-region traffic needed, with no upfront costs or software purchases required. Fully integrated, pglogical requires no triggers or external programs. This alternative to physical replication is a highly efficient method of replicating data using a publish/subscribe model for selective replication.
pglogical is supported for Aurora PostgreSQL 2.6.x or higher (compatible with PostgreSQL 10.13 or higher), and Aurora PostgreSQL 3.3.x or higher (compatible with PostgreSQL 11.8 or higher). Please review the Aurora documentation to learn more. You can view a list of all PostgreSQL extensions supported on RDS on the AWS User Guide.
Amazon Aurora combines the performance and availability of high-end commercial databases with the simplicity and cost-effectiveness of open source databases. It provides up to three times better performance than the typical PostgreSQL database, together with increased scalability, durability, and security.
