I believe the vault and the indexers also use storage0.euwest.azure as read-only archive backend. We don't want to switch them over to cassandra (at least not until the replay has completed, if ever).
I think we should inline the cassandra storage config in the webapp0 swh.web config instead.
We should also make sure that the optional cassandra dependencies are pulled in by the storage deployment (unless swh.storage grew hardcoded dependencies on the cassandra stuff, in which case we're fine).

I agree with @olasd. Another possibility is to run an swh-storage instance on webapp0.

Right.
I also wanted to make sure i did not misconfigure. Nobody shouted at it so it seemed fine from that standpoint ;)
Thanks.

yes, not sure what's the best here though.
I'll go with the first proposition for no other convention than 'dibs' :D

btw, yeah.
I believe i started working on that [1]
For some unknown reasons yet, i don't see the python-cassandra-driver (buster) uploaded in pergamon.
Don't know if it's related or not, It's marked as source, i need to continue the work on that [2]

Thanks to @olasd, we saw everything is fine in the end.
I looked for the wrong package ;)
python-cassandra-driver is the source package
python3-cassandra is what we want though \m/
root@pergamon:/srv/softwareheritage/repository# reprepro ls python3-cassandra python3-cassandra | 3.20.2-1~swh1~bpo10+1 | buster-swh | amd64

i realize i did not deal with that part though...

- Properly switch to webapp0's storage to cassandra storage
- Add conditional to install the python3-cassandra when needed

you're making the cassandra driver in the same process as the webapp. Are you sure you want to do that?

No idea yet, i did what i said i would do.
Also i would like to try and see what happens.
And then improve on what's problematic.
That would still be progress ;)

| 106–109 | Could you move that package stanza into a new include ::profile::swh::deploy::storage::cassandra instead? That way we can do the same change to the swh::deploy::storage (and avoid dependency conflicts). | |

Move the cassandra storage's dependencies to a profile
- Install conditionally on webapp node if configuration requires it (for webapp0).
- Install conditionally on storage node if configuration requires it (nobody for now)
