Summary
In this chapter, we discussed SkyTools, a tool package provided and developed by Skype. It provides you with generic queues (pgq) as well as a replicator called Londiste. In addition to these, SkyTools provides walmgr, which can be used to handle WAL files.
The next chapter will focus on Postgres-XC, a solution capable of scaling reads as well as writes. It provides users with a consistent view of data and automatically dispatches queries inside the cluster.
