Document general workflow for bringing new data into the warehouse (external table etc.)

Closed this issue · 0 comments

As a contributor to the Cal-ITP warehouse, I want the end-to-end workflow for updating the schema of existing data to be documented so that others in the ecosystem can maintain a data source after my engagement has ended.

This specific request came via @kengie who wants to ensure that the protocol for updating the data added in #3129 is clear to future maintainers of that data; the request overlaps with documentation work I am currently doing for NTD data per a conversation with @evansiroky and @tiffanychu90.

Acceptance criteria:
Documentation saved in a central location (probably docs.calitp.org) for:

  • How to update an external table
  • How to update staging & downstream tables
