DynamoDB

Overview

Amazon DynamoDB is a managed NoSQL database service that's offered by Amazon as part of the AWS portfolio.

Example use case

You currently use DynamoDB to store metrics on product use and growth, but being stuck in the DynamoDB silo means that you can't easily use this data across a range of business use cases or teams. You can use a batch sync to liberate your data into Cinchy.

tip

The DynamoDB source supports batch syncs.
