Singer is an open-source ETL framework maintained by Stitch Data. The core concepts of Singer revolve around “Taps” (data sources) and “Targets” (destinations), which are executed as Bash commands.
Taps and Targets
A full list of Taps and Targets can be found in the Singer Github.
These Taps and Targets are also available for installation via PyPi.
An example of using the Singer Operator can be found here.
