Q1. MongoDB is one of the most popular, widely adopted databases. What are the pros and cons of using MongoDB? MongoDB has grown to be one of the most widely-adopted NoSQL databases for JSON-like documents across many industries. MongoDB’s document model and API align closely with how many applications produce and consume data, and its developer experience and broad ecosystem of supporting libraries and integrations make it a natural choice for many use cases. However, MongoDB’s underlying architecture is not optimized for in-app analytics or any query involving large numbers of documents in c ..read more

Q1. What is Amazon DocumentDB (with MongoDB compatibility)?  Amazon DocumentDB (with MongoDB compatibility) is a fast, scalable, highly available, and fully managed document database service that is purpose-built to store and query JSON. Amazon DocumentDB is engineered with scalable workloads in mind, and allows compute and storage to scale independently. You can easily scale read capacity to millions of requests per second by adding up to 15 low latency read replicas across three Availability Zones (AZs) in minutes, regardless of data size. Amazon DocumentDB scales to 64TiB automati ..read more

In relation to mobility, let me share an example: At MIT Senseable City Lab, we analyzed all taxi trips that connect the City of New York in a given year. The project-called HubCab– gathered 170 million taxi trips by over 13,000 Medallion taxis in New York City ..read more

BY Adamo Tonete   | October 16, 2017 | In this blog post, we will talk about MongoDB sharding and walk through the main reasons why you should start a cluster (independent of the approach you have chosen). Note: I will cover this subject in my webinar How To Scale with MongoDB on Wednesday, October 18, 2017, at 11:00 am PDT / 2:00 pm EDT (UTC-7). Sharding is the most complex architecture you can deploy using MongoDB, and there are two main approaches as to when to shard or not. The first is to configure the cluster as soon as possible – when you predict high thro ..read more

NoSQL by the numbers BY Matt Aslett, research director, 451 Research Since the third quarter of 2012, 451 Research has been tracking the mentions of NoSQL databases in LinkedIn profiles. It is a fairly crude but nonetheless interesting measure of the relative popularity of the various NoSQL databases. There has been a clear leader throughout this period, with MongoDB growing from 43% of all mentions of NoSQL technologies in LinkedIn profiles in Q3 2012 to more than 50% in Q2 2015. To be clear: MongoDB is mentioned in more LinkedIn profiles than all of the other NoSQL databases put together. If ..read more
