I look for a versatile, Open-Source ETL solution. Having researched many options, we have selected Singer and Meltano for prototype, and currently are still in prototype stage. With this, people in this Slack community were extremely helpful; most help came from @Edgar Ramírez (Arch.dev) but also others. I have now published a short article documenting our journey and the decision process why Singer and Meltano was preselected. Comments and feedback alwayls welcome. https://medium.com/@pp_85623/towards-the-killer-open-source-elt-etl-4270df7d3d93
