Who This Book Is For

This book is ideal for PostgreSQL administrators who want to set up and understand replication. By the end of the book, you will be able to make your databases more robust and secure by getting to grips with PostgreSQL replication.

What You Will Learn

• Use Point-in-time Recovery to perform data recovery as well as replication
• Set up synchronous as well as asynchronous streaming replication
• Get familiarized with the transaction log, the core component of most replication setups and its purpose
• Improve speed and reliability with an understanding of pgpool and PgBouncer
• Increase your data security and geographically distribute data
• Make your systems more available and secure with Linux High Availability
• Scale out with PL/Proxy and Postgres-XC
• Detect, investigate, and solve replication-related problems

In Detail

PostgreSQL offers a comprehensive set of replication related features. Unleashing the power of PostgreSQL provides you with countless opportunities and a competitive advantage over other database systems.

This book will guide you through the most important concepts of PostgreSQL replication. It contains all the information you need to design and operate replicated setups.

Beginning by giving you an understanding of replication concepts, the PostgreSQL transaction log, and Point-in-time Recovery, we gradually move on to setting up asynchronous and synchronous replication. Next up, you will learn to monitor a PostgreSQL cluster setup, deal with monitoring tools, and then move on to understanding Linux High Availability. Further, we explore widely-used tools such as Slony, SkyTools, Postgres-XC, and walbouncer, and set up PL/Proxy.

Finally, you'll get acquainted with the new technology of BDR, which allows bidirectional replication in PostgreSQL.
