Having introduced Slony, we will take a look at another popular replication tool. SkyTools is a software package originally developed by Skype, and it serves a variety of purposes. It is not a single program but a collection of tools and services that you can use to enhance your replication setup. It offers solutions for generic queues, a simplified replication setup, data transport jobs, as well as a programming framework suitable for database applications (especially transport jobs). Covering all aspects of SkyTools is not possible here. However, in this chapter, the most important features, concepts, and tools are covered to show you an easy way to enter this vast world of tools and ideas and benefit as much as possible.
In this chapter, we will discuss the following topics related to SkyTools:
Building generic queues
Using londiste for replication
Handling XLOG and walmgr
As with all the chapters of this book, the most recent version of SkyTools will be used.
