Summary
The user is inquiring about documentation on Artifacts, specifically whether a provided link contains complete resources and if all artifact metadata is tracked in the data catalog during executions. They reference a previous discussion about notifications and express interest in the benefits of using SQS/SNS for artifacts, despite not having those services enabled. The user mentions working on a comprehensive end-to-end document and seeks ideal example catalogs. They ask for any available source information in the meantime, noting that the current implementation is internal to Union and that the open-source implementation relies on contributions from various teams. The user acknowledges the Union announcement and the impressive UI work but is uncertain about the backend plumbing, given that annotations are part of open-source Flytekit, which are intended to support development. They note that the backend will be pluggable.
