T2967: Write journal client subcribed to origin_visit_status topics
Commits
rDSCH9395aa0763b7: scheduler.cli.journal: Add `swh scheduler journal-client` cli
Summary

This adds the cli entrypoint to actually process origin_visit_status topic (which writes
to the origin_visit_stats db table).

Note that:

  • the cli name visit-stats could be changed if someone has a better name in mind
  • this does not open the swh.journal as optional dependency for the scheduler

which may be a tad cumbersome

Related to T2967
Depends on D4873

I guess we could just call this swh scheduler journal-client (single command at the top level of swh scheduler), until we need another one of these (in which case we can move them both to a subcommand of swh scheduler journal-client).

The rest looks like journal client boilerplate, which is totally fine by me!

I guess we could just call this swh scheduler journal-client (single command at the top level of swh scheduler),
until we need another one of these (in which case we can move them both to a subcommand of swh scheduler journal-client).

The only small thing with this is that we kinda lose the notion of visit-stats as we
pass no object type in that current implementation (granted that can be fixed
with a docstring though).

I also forgot to mention here that @douardda suggested to invert the command
subcommand names to swh scheduler visit-stats journal --help as journal is an
implementation detail.

Given that, we could go a tad further and even drop the journal notion and replace it
with compute or process or some such.

swh scheduler visit-stats process

which seems to the point of what we do here, we are processing visit-status to aggregate
them into visit-stats.

+1 for swh scheduler journal-client, for consistency with other packages + we may want to add other stuff in that client.

And we can rename it later if needed

which seems to the point of what we do here, we are processing visit-status to aggregate

I think journal-client would be more explicit than process (and consistent with other modules), even if it "leaks" an implementation detail (but in any case, you'll need a journal client configuration to run the tool, so I don't think that's really an issue).

I guess my main objection to that command name is that I don't like the "visit-stats" name (there's not a single statistic in any field of that table!). I don't have any better suggestion for it anyway, so that's not a very relevant objection to naming the thing that keeps that table up to date. I'm not a huge fan of having a command group with a single sub-command either, which is another objection, but I guess we will want to add a query function or two as subcommands there anyway.

All in all, I:

  • strongly prefer that this command be named journal-client
  • don't much care if it ends up being a visit-stats subcommand, as long as it's consistent with the table name and it doesn't stay "alone" forever.
