Depending on the type of destination you’re using, Stitch may deconstruct these nested structures into separate tables. [November 2016] Removed all mentions of the lack of local emulator for DocumentDB as Microsoft announced the general availability of such a local development version. MongoDB was also designed for high availability and scalability with auto-sharding. MongoDB is a document database that stores data in flexible, JSON-like documents. DocumentDB is a NoSQL database-as-a-service this is part of the Microsoft Azure platform. Hadoop is an open-source platform, which is used to store and process the huge volume of data. A data lake, on the other hand, does not respect data like a data warehouse and a database. That’s a standard format used by most NoSQL databases (hey, even SQL Server speaks JSON! The main technical lock-in you have to deal with is the query interface: each database has its own way of querying documents. Nested JSON Data Structures & Row Count Impact MongoDB and many SaaS integrations use nested structures, which means each attribute (or column) in a table could have its own set of attributes. So let’s take mLab, a MongoDB PaaS offering, as a point of comparison. A data lake, on the other hand, does not respect data like a data warehouse and a database. Use CData Sync to customize and automate MongoDB data replication to Azure Data Lake. But we should be careful not to compare apples and oranges here: DocumentDB belongs to the PaaS family whereas MongoDB is a database, not a service. It is more analogous to Amazon Athena,” says Baer.

Reducing Data Silos: The on-prem data lake is the only realistic approach to the original promise of a data lake (a single repository for ALL your data). Those server-side functions can take 3 different forms: Now MongoDB can execute server-side Javascript as well, but my understanding is that: MongoDB’s documentation clearly states that there are performance limitations in executing server-side Javascript; in comparison, DocumentDB is really designed for this purpose as it pre-compiles your Javascript code, then stores and executes the resulting bytecode. That’s obviously beyond DocumentDB’s core features and is related to its PaaS nature, but I don’t believe there is any service provider offering such geo-distributed setup for MongoDB (at that cost and ease of use). If you want to do both frequent and fast data retrieval and perform analytics, duplicate the data … MongoDB support for VS Code is provided by the MongoDB for VS Code extension. I feel that DocumentDB usually doesn’t get considered when making this decision although its characteristics make it a serious contender to MongoDB, even offering stronger advantages in some situations. 3.
