Introduction to the MongoDbDataProvider Module

The MongoDbDataProvider module provides a dataproviderintro "data provider" API for MongoDB servers. It uses the builtin mongodb module which wraps libmongoc for efficient communication and provides full CRUD operations, aggregation pipelines, and bulk operations.

This data provider provides MongoDB API access to:

• databases: databases/{database_name}
• collections: databases/db_name/collections/{collection_name}
• CRUD operations: databases/db_name/collections/coll_name/{insert, find, update, delete}
• aggregation: databases/db_name/collections/coll_name/{aggregate}
• bulk: databases/db_name/collections/coll_name/{bulk}

MongoDB Data Provider Factory
