Create a cloudant DB with Node-RED

I want to create a new Cloudant DataBase with Node-RED to store data send by different boards. Each board has different ID and I want to create a new DB for each new ID.

Currently, I can add data on Cloudant but a DB must be specified. Does any one know how to create a new DB wether ID is not known ?

Solution

  • You can not do this with the current Cloudant nodes.

    The connection to the database is held open from when Node-RED starts to when it shuts down, it is not opened and closed for each update/query.

    The easiest way to solve the problem is just to include the board id in each update so that you can just adjust the filter to return information for a specific board.

    You can then pass in the board id into the query to get the right data back.
