MongoDB Map Reduce: Yet another tutorial

As the title says, this is yet-another-tutorial on Map Reduce using MongoDB. But two things that are different here:

  1. A problem solving approach is used, so we’ll take a problem, solve it in SQL first and then discuss Map Reduce.
  2. Lots of diagrams, so you’ll hopefully better understand how Map Reduce works.

If MapReduce still didn’t click, you could try this SQL to MongoDB MapReduce guide.

Membase: Quick Getting Started Videos

Two short videos on setting up ☞ a single Membase node (aprox.2 min) and ☞ a Membase cluster (aprox.3 min). As you can imagine this is just the very very basics. But on the other hand it is kind of cool to know that’s so easy to get it up and running.

Membase Intro

An intro slidedeck to Membase:

Actually I’d say that the second part is much more than an intro, providing details on:

  • Membase data flow
  • data buckets
  • vBuckets (nb see more about virtual buckets)
  • persistence behavior (memory for hot data, disk for cold data)
