Is any cleanup implementation needed for long term usage? (R2, D1)

[rgembalik]

I started playing around opennextjs-cloudflare recently and so far I had many successes. However, after couple deployments, I noticed, that the R2 usage keeps growing. This spun the following question:

Do I need to create any lifecycle policy for R2 cleanup?

I couldn't find anything in documentation about that. I also couldn't find any information about safety of removing r2 objects.

I think it would be good to have those questions answered in the docs:

• Is it expected for the size of the storage to grow over time?
• Is it safe to setup lifecycle policy that removes r2 objects after e.g. 30 days?
• Will my website break if the R2/D1 storage is cleared manually

If I missed anything in the documentation that already describes it, I will be grateful for pointing that out.

That's a good question.

R2 holds cache artifacts and they are keyed by build id (which changes on every build).

You probably want to keep the last few (days of) data if users have loaded an old version of the site and still interacts with it.

R2 currently does not support deleting keys by prefix but we are looking into it

Quick update: deleting by prefix is on the R2 team roadmap.
I'll update when we get further update about the status.
