I am looking at various extractors and loaders on Meltano Hub and to be frank it’s a really interesting project . But I wonder is there any evaluation criteria for these connectors to make it to the Meltano Hub ? By evaluation I mean does Meltano evaluate how an extractor implements the Security , Privacy and Data Handling aspects before adding it to the hub and being subsequently used by users for their projects.

As we continue to grow Meltano, we’re investing more in the overall Singer ecosystem. Right now we do basic testing on all of the connectors to verify that they can install and accept the expected commands (see https://github.com/meltano/hub/pull/1052 as an example). The majority of the connectors on the Hub right now are community maintained and have varying degrees of quality. Those that are built on the Meltano Singer SDK are better hardened along the dimensions you highlighted, and the connectors that Meltano ourselves are starting to maintain (postgres, snowflake, and other DBs) will have those guarantees. We’ll definitely be adding more information over time to the Hub to make all this clearer and give the community more confidence in each of the connectors. Does that help answer your question?
