rDDATASET058e568492ba: Add luigi tasks
Summary

They are more tuned toward running automatically, as they call each
other as needed, and can be imported by workflows defined in other
modules (eg. the future swh.graph.luigi module).

This massively re-uses the CLI, so most of the code is:

  • telling Luigi how to deduplicate + when/how to reuse output of tasks that already ran
  • adding stamp files to avoid accidentally using a partially written export (because it was interrupted midway)
  • the meta.json file, which acts as a final stamp and provides information about the dataset export itself (required for T2579)

Depends on D8828

Test Plan

This is mostly declarative code, and all the issues are when interfacing
with external stuff (mostly S3 and Athena), so I do not think writing tests
is worth it.

I played with this code in various scenarios while debugging, so I am
confident task deduplication works fine.

lgtm

one typo inline.

Overall, that feels like luigi is a kinda "distributed makefile" (with a python dsl).

...so I do not think writing tests is worth it.

only time will tell if you are right ;)
