It would be great if you could expose the ListTables API operation on your DynamoDB resources in addition to the currently supported APIs of GetItem, PutItem, etc. In general, if there was a 1-1 mapping of available DynamoDB API operations from the AWS SDK to the Retool UI, it would be very helpful for us.
Hey @chpeters, welcome to the community!
We do have an internal ticket tracking this that I've just bumped to get some eyes on. It's not on the roadmap as we are currently only supporting operations against a specific table today. But, we'll update this thread with any additional information as we receive it. Thanks!
