Category: PostgreSQL

The training focuses on the management of PostgreSQL large size databases, working in conditions requiring high availability. We discuss the issues of correct implementation of HA (High Availability) system for PostgreSQL and techniques which are intended to distribute application load over several servers. We will give some reliable recipes for systems that could survive the failure of the infrastructure’s part without disrupting their work.

The training programme includes analysis of the available PostgreSQL replication methods and practical examples of embedded replication usage. We will accurately explain the difference between synchronous and asynchronous replication and we will analyse the advantages and disadvantages of each solution. We will not forget about comprehensive approaching the issue of monitoring, without which HA systems cannot do.

Our instructors have many years of experience with PostgreSQL, both as administrators and as programmers. One of our trainers is a PostgreSQL contributor and a regular speaker at the world’s largest conference on the topic.
