Amazon DocumentDB (with MongoDB compatibility) is a fast, scalable, highly available, and fully managed document database service that supports MongoDB workloads. You can use the same MongoDB 3.6 application code, drivers, and tools to run, manage, and scale workloads on Amazon DocumentDB without having to worry about managing the underlying infrastructure. As a document database, Amazon DocumentDB makes it easy to store, query, and index JSON data. AWS built Amazon DocumentDB to uniquely solve your challenges around availability, performance, reliability, durability, scalability, backup, and more. In doing so, we built several tools, like the profiler, to help you run analyze your workload on Amazon DocumentDB. The profiler gives you the ability to log the time and details of slow-running operations on your cluster. In this post, we show you how to use the profiler in Amazon DocumentDB to analyze slow-running queries to identify bottlenecks and improve individual query performance and overall cluster performance.

In their own words, “Contura Energy is a Tennessee-based coal supplier with affiliate mining operations across major coal basins in Virginia, West Virginia, and Pennsylvania. We export metallurgical coal, a key raw material in steelmaking, to customers on five continents and approximately 25 countries.” Contura chose to run the blockchain network on Amazon Managed Blockchain because it’s a fully managed service that scales automatically, as needed, and removes a lot of the heavy lifting needed to operate a blockchain network. Additionally, you can easily integrate Managed Blockchain with other AWS services, and Managed Blockchain simplifies growing and administering the blockchain network. Network governance and inviting new members can be done via the AWS Management Console, and each member is billed separately based on their own usage.
