Call for presentations

Thanks to all who came out for the meetup tonight! We had a great general discussion about all kinds of things related to MongoDB in this question/answer session.

It would be great to get more speakers for future meetups. We came up with a list of possible topics at the end of the meeting tonight. Anyone want to claim a topic and present to the group? Or you're welcome to suggest a topic you have experience with, and that would be of general interest to the group.

Here's the list we came up with:


  • Sharding - what is it? how to choose a good shard key? schema design with sharding, etc.
  • Effective use of namespaces (choosing database and collection names wisely)
  • Different uses of documents and the benefits/pitfalls of each (i.e. small flat documents vs large rich documents)
  • Security
  • Durability and consistency
  • Indexing (how to choose an index, compound indexes, how indexes work in general)
  • Algorithms for precomputing
  • Querying (how to use the query language, gotchas, designing your schema for how you will query)
  • When to use MongoDB (or nosql in general) and when to use a relational database (pros and cons of each)
