MongoDB User Group

We have two great talks lined up for this week.  We'll be starting the first talk at 6:45.  See you all in a few days...

1) Luke Shannon will be giving a talk on how tools within the Jaspersoft suite can be used to run reports from MongoDB

2) A 10gen engineer will be giving a talk on Schema Design by Example:

"One of the challenges that comes with moving to MongoDB is figuring how to best model your data. While most developers have internalized the rules of thumb for designing schemas for RDBMSs, these rules don't always apply to MongoDB. The simple fact that documents can represent rich, schema-free data structures means that we have a lot of viable alternatives to the standard, normalized, relational model. Not only that, MongoDB has several unique features, such as atomic updates and indexed array keys, that greatly influence the kinds of schemas that make sense. Understandably, this begets good questions: Are foreign keys permissible, or is it better to represent one-to-many relations withing a single document? Are join tables necessary, or is there another technique for building out many-to-many relationships? What level of denormalization is appropriate? How do my data modeling decisions affect the efficiency of updates and queries? In this session, we'll answer these questions and more, provide a number of data modeling rules of thumb, and discuss the tradeoffs of various data modeling strategies."

    I would like to hear about the various kinds of indexes, and foreign-key-type constructs

    The topics I'm most interested in are:

    1) Planning and maintaining shards and replica sets (but not the basics of setup).

    2) How to determine which MongoDB stats matter to you.

    For me:
    - Sharding (Setup, maintenance and scaling)
    - Managing fail over of replica sets (best practices)
