What’s under the hood?• The first time mongeez runs in a new environment it creates a collection in your database called mongeezMember FINRA | MSRB | SIPC © 2012 SecondMarket Holdings, Inc.Member FINRA | MSRB | SIPC © 2012 SecondMarket Holdings, Inc.

What’s under the hood?• The first time mongeez runs in a new environment it creates a collection in your database called mongeez• All changeSets are then executed; as each one is executed it is recorded in the mongeez collection atomically, so it can run in a clustered environment• The next time you run mongeez in that environment, it iterates through all changeSets in your XML file, but will only execute changeSets that have not been run previouslyMember FINRA | MSRB | SIPC © 2012 SecondMarket Holdings, Inc.Member FINRA | MSRB | SIPC © 2012 SecondMarket Holdings, Inc.

Other things we have used mongeez for • For running your ensureIndexes on every deploy (using alwaysRun flag) or anything you would like to run on startup in Mongo • For ensuring static data is in place Member FINRA | MSRB | SIPC © 2012 SecondMarket Holdings, Inc.
