Book Description
Replication is an advanced subject but this tutorial makes it so simple to assimilate thanks to a carefully structured approach based on examples and screenshots. As a PostrgreSQL administrator it will expand your horizons.
  • Explains the new replication features introduced in PostgreSQL 9
  • Contains easy to understand explanations and lots of screenshots that simplify an advanced topic like replication
  • Teaches PostgreSQL administrators how to maintain consistency between redundant resources and to improve reliability, fault-tolerance, and accessibility
In Detail
PostgreSQL offers a comprehensive set of replication related features, which can be used to make your database servers more robust and way more scalable. Unleashing the power of PostgreSQL provides the user with countless opportunities and a competitive advantage over other database systems. To make things more powerful, PostgreSQL can be used in conjunction with a handful of sophisticated tools serving various different needs such as queuing, logical replication, or simplified transaction log handling.
"PostgreSQL Replication" is a practical, hands-on guide to PostgreSQL replication. It will provide you with the theoretical background as well as simple examples showing you how to make replication work on your system. A broad toolchain will be presented along with mature PostgreSQL-core technology.
"PostgreSQL Replication" starts with an introduction to replication concepts as well as the physical limitations of different replication solutions. You will be guided through various techniques such as Point-In-Time-Recovery, transaction-log-based replication and you will be introduced to a set of replication-related tools. In the final chapter you will learn to scale PostgreSQL to many different servers using PL/Proxy.
You will learn how to reset PostgreSQL to a certain point in time and figure out how to replicate data in many ways. You will deal with both synchronous as well as asynchronous replication. In addition to that, the book covers important topics, such as Slony, and upgrades with virtually no downtime. We will also cover important performance-related topics to make sure your database setups will provide you with high speed AND high availability.
"PostgreSQL Replication" contains all the information you need to design and operate replicated setups. You will learn everything you need to know for your daily work and a lot more.
