I want to filter my device data through a rule engine where I apply different actions to it before storing and displaying it to the user. I need to store this data into a time series database and I also need to display it in near real time. This is the data flow that I think is necessary. Anyone have an architectural example they can recommend? I am looking at ThingsBoard at the moment.
You can use TIG architecture. TIG stands for Telegraf, InfluxDB and Grafana. There are many tutorials avilable online on how to configure this architecture. You can follow this medium article.
The architecture of this looks as shown in the below image. You can have all your rules in the telegraf stack. You can also configure telegraf such a way that it can act as bridge between different protocols. In this example, I am using it as a bridge between MQTT broker and InfluxDB. You can through in a little python or shell script that can handle your rules.
Have you considered the AWS ecosystem for this ? i.e, a combination of IoT Core, kinesis, timeseries DB, etc ?
