Presentation: An introduction to node.js and Riak

While most of Francisco Treacy’s (@frank06) “An Introduction to node.js and Riak” presentation is focusing on the advantages of event-based architectures, it also shows how to integrate node.js and Riak using ☞ riak-js, a node.js library for Riak that takes advantage of the friendly HTTP-based Riak protocol

There are a couple of other interesting things that can be learned from this slide deck. For example the cost of I/O:

simply described afterwards:

In other words, reaching RAM is like going from here to the Red Light District. Accessing the network is like going to the moon.

Update: thanks to a comment on this post, here is what Googler Jeff Dean presented on the cost of I/O:

But as Frank mentions, there are some risks while working with cutting-edge technologies:

  • Cutting-edge technologies are not bug-free
  • Riak still has some rough edges (some in terms of performance)
  • node.js is approaching its first stable version
  • asynchronous JS code can get “boomerang-shaped”
