The tool is based upon @corpglory/tsdb-kit (also created by CorpGlory team), which provides a unified interface and the same output format for each datasource, such as field order and time units.
Imagine you have a Grafana dashboard with a nice metric and a query for it. If you want to use the same data that you receive via this query in any other case (import to another database, plot a new graph in any other tool, make a custom model for Hastic , etc.) - the simplest way would be to export your data to a .csv file. You can do it using a standard exporting tool, but on massive datasets, the dashboard can get overloaded. Standard exporting tool only can be used in Graph and Table panels < Grafana 7 version.
The project started with a request from Andrew Eberbach from Ebertech. He wanted a tool for exporting data from InfluxDB in the background, after delivery we extended the support to other datasources and made @corpglory/tsdb-kit.
