Hi, I have quickly read the document of Ditto. In my understanding, Ditto allow consume data from kafka or MQTT server to get the latest status of a Things (or, a device), and provides API to let users know the latest value of a device's feature (measurement concept in IoTDB).
I think it is easy to persist the data into IoTDB meanwhile. But if we want to provide high write performance (e.g., more than 10 million data points per second), we may need to use batch_write api, which is a little complex. Another thing that need to be discussed is that as ditto does not have api for query historical data. we have to design and add one. The third is, it sounds that Ditto does not require K8s and Keycloak Authentication. I quickly searched Keycloak and find it is a solution for Identity and Access Management. Hmm... IoTDB has a user/role management module, but does not support Keycloak... I think currently the community lacks committers to develop this feature..... But we can create an issue about that, and maybe some familiar guys can do it.
