We're starting to expand functionality. One of the keys for Maggma will be connecting to a lot of different data sources but leveraging the powerfull querying in MongoDB. The GridFS concept of an index + bucket storage patterns really well to other cloud storage platforms that we hope to support.
Changes:
- Added an AmazonS3 Store
- Added from_collection in mongostore to instantiate a MongoStore from a PyMongo Collection object
Warning: This object will not serialize and deserialize properly so don't expect this to work with MPI building or saving to files - Fixed distinct and groupby to be applicable to all stores.
