DynamoDB is a fully managed NoSQL database available in AWS. It’s a convenient and scalable way to store large amounts of data and retrieve it efficiently, all at extremely reasonable prices. For machine learning and data science applications, it provides a great way to publish models and results. For analytics and log processing, it makes it easy to store and serve aggregates and rolled-up data.
DynamoDB is an excellent target data store when using Mortar. Mortar’s Hadoop is powered by Amazon EMR, so the data will stay entirely within AWS. Everything scales up with you. As you need to process more data, just bump up your Mortar cluster size and DynamoDB throughput.
