My name is Kranthi Kiran Burada, and I've been serving as a Database Migration Specialist at AWS for the past 6 years, accumulating a total of 11 years of experience in the field. My primary focus lies in assisting customers with migrating from commercial databases to open-source databases like PostgreSQL.
Over the last 8 years, I've been deeply involved with PostgreSQL, aiding clients in performance optimization, database design, troubleshooting, and offering best practices during migrations from Oracle/SQL Server to PostgreSQL.
Additionally, I have the privilege of being an AWS Certification Subject Matter Expert (SME), contributing to the development of all AWS associate certifications and the AWS Database Specialty Certification.
Database replication plays a crucial role in ensuring data availability, scalability, and disaster recovery in modern distributed systems. PostgreSQL, a widely-used open-source relational database management system, offers various replication methods to synchronize data across multiple nodes. This session explores the concept of selective column replication, a technique that allows replicating specific columns of a table rather than the entire table, in PostgreSQL. We delve into the rationale behind selective column replication, its benefits, challenges, and implementation strategies within the PostgreSQL ecosystem. Additionally, we discuss practical use cases where selective column replication can significantly enhance database performance, reduce network bandwidth consumption, and facilitate efficient data synchronization in complex distributed environments. Through this exploration, we aim to provide insights into leveraging selective column replication as a powerful tool for optimizing PostgreSQL database replication strategies.
