This month we have not one, but two talks.
How to Scale MongoDB - Trisha Gee @trisha_gee (in English)
This month is March Madness (http://www.lczajkowski.com/2013/11/25/mongodb-mug-march-madness/) - we aim to get a MongoDB Engineer to every MUG in March. Fortunately you have one living right here in Seville. Trisha will give a short, high-level talk on the things that make MongoDB scalable - what's a Replica Set? What does Sharding mean?
Stop blaming MongoDB and start thinking about design - Javier Baena @JvrBaena (in Spanish)
When using MongoDB in a large project like SocialBro (http://www.socialbro.com/), we learnt the hard way that most of the time, you blame MongoDB for things you should have planned/designed better. We'll review some of the pitfalls we faced on model and architecture design that have a direct impact on performance, and give some tips, based on our experience, on how to avoid them and how to start blaming yourself and not MongoDB
Javier Baena is Backend developer in SocialBro, lives in Seville, and works daily with technologies like Node.js, MongoDB, Redis, etc
