Description
Due to the massive amount of time series managed at the edge and the disconnected nature of operations, a native time series database is necessary as part of EdgeX. MongoDB is not an optimal fit for huge amount of time series data.
The TSDB is useful for local storage and shall be easily interfaced with open source visualization tools (e.g. Grafana) and open source analytics platforms (e.g. Flink).
InfluxDB is an open source TSDB distributed under MIT License which can be integrated as part of the solution.
Requirements
- Ability to send data to a local remote InfluxDB instance
- Ability to send data to a remote InfluxDB instance
- Ability to send data to multiple InfluxDB instances (up to 3)
Design
Although the best option would be to modify Core Data Service in order to rely on InfluxDB instead of MongoDB, a first step to achieve integration with influx is to modify the existing Export Service in order to enable a new delivery via InfluxDB Go Client
Code
To be updated.
Current status
Waiting for Go Export Client & Distribution to be finalized by the appointed group before making the contribution
