Tableau web data connector
Tableau 9.1 includes the Web Data Connector, which lets you build connections to data - including HarperDB. With this feature, you can connect to almost any data accessible over HTTP including internal web services, JSON data, and REST APIs.
You can use the Tableau Web Data Connector Software Development Kit (SDK) to build connectors with Javascript and HTML. And since you control how the data is fetched, you can even combine data from multiple sources.
The SDK includes templates, example code, a test simulator, and documentation. We’ve also created a place where Tableau users can share connectors and collaborate on new ideas.
The repository for the Tableau web data connector is here https://github.com/tableau/webdataconnector
