We have a small IoT project underway using DynamoDB and it appears re:dash may offer exactly what we need. I have used your eu-west-1 AMI and updated it to the latest version, filled out the datasource with my DynamoDB connection information and I have used an IAM role with the instance as well as trying access keys. I think the connection is OK as when I run DQL queries from the command line it returns a result. However I cannot get the query tool in the web frontend to return anything. It either runs for < 1s and returns nothing or runs forever.
I am just trying something simple like SCAN * FROM rider;
I understand DynamoDB support is a recent addition and there is limited to no documentation. I would really appreciate some pointers on how to get some queries working please.
