DynamoDB
Amazon DynamoDB is a managed NoSQL database service that is 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 in order to liberate your data into Cinchy.
The DynamoDB source supports batch syncs.
You can review the parameters that can be found in the info tab below (Image 1).
Parameter | Description | Example |
---|---|---|
Title | Mandatory. Input a name for your data sync | Product Metrics |
Version | Mandatory. This is a pre-populated field containing a version number for your data sync. You can override it if you wish. | 1.0.0 |
