Do you plan on integrating with metadata sources as well such as Amundsen or Datahub? Or is the plan that DLT will become the metadata source?
At the same time, dlt is a pipeline building tool first - so if people want to read metadata from somewhere and store it elsewhere, they can.
If you mean to take metadata like we integrate with arrow - that remains to be seen if the community might want this or find it useful, we will not develop plugins for collecting cobwebs, but if there are interested users we will add it to our backlog.
We have a PR (https://github.com/dlt-hub/dlt/pull/594) that is about to merge that makes the above highly configurable, between evolution and hard stopping: - you will be able to totally freeze schema and reject bad rows - or accept the data for existing columns but not new columns - or accept some fields based on rules'
