About TSDB Data Service API V2.1¶

Starting from the EnOS 2.1.3 internal build, the TSDB Data Service API version is upgraded to V2.1.

The EnOS Time Series Database (TSDB) data service provides the interfaces listed below for developers to invoke for data and application development. EnOS TSDB provides efficient and stable storage management for time series data that is ingested from devices or generated by the stream processing engine. Currently, EnOS TSDB can store the following types of asset data:

Original data of AI measurement points
Minute-level normalized data of AI measurement points
Device status (DI) data
Device status duration data
Generic data
Power consumption/production data

For more information about TSDB storage, see Managing Time Series Data.
