7pm: "The Modulestore: Storing edX Courses in MongoDB" by John Eskew

John Eskew is a software developer on the Core Platform Team at edX. Using MongoDB, they've created the concept of a "modulestore" which stores all the course modules using a particular schema. The initial modulestore stored each module as a document and supported two branches per course - a draft and published branch. The newest implementation supports multiple branches, keeps all past course revisions, and has a different schema designed with our typical query patterns in mind. The edX platform also stores course asset BLOBs in MongoDB via GridFS.
