Databases are nothing without the data they store. In the event of a failure - catastrophic or otherwise - immediate recovery is essential.
By carefully combining multiple servers, it’s even possible to hide the fact a failure occurred at all.From hardware selection to software stacks and horizontal scalability, this book will help you build a versatile PostgreSQL cluster that will survive crashes, resist data corruption, and grow smoothly with customer demand. Then it’s on to preventing downtime as well as troubleshooting some real life problems that administrators commonly face.
Next, we add database monitoring to the stack, using collectd, Nagios, and Graphite. And no stack is complete without replication using multiple internal and external tools, including the newly released pglogical extension.
We even round off by tackling the complex problem of data scalability.This book exploits many new features introduced in PostgreSQL 9.6 to make the database more efficient and adaptive, and most importantly, keep it running.
