How do I limit cache disk usage?

[acejam]

Hello,

i'd like to use Souin with Caddy and leverage one of the disk-based storage adapters - such as Badger or NutsDB.

In an effort to prevent "out of disk" system errors, how can I limit the amount of disk space that can be used by the cache?

Hey @acejam I think that's not possible ATM with these storages. Maybe we could implement the directory size in the simplefs storage https://github.com/darkweak/storages.

Thanks for the idea. Is the size parameter not used for this already? https://github.com/darkweak/storages/blob/main/simplefs/simplefs.go#L73

The size is about the number of objects to store but it doesn't limit the filesystem size.

Hi @darkweak - it looks like this PR that you're working on might help? darkweak/storages#20

I would be interested in testing this.

Hey @acejam you should be able to use it using

{
    cache {
        ttl 86400s
        simplefs {
            path /somewhere/files/path
            directory_size 1MB # to limit to 1 megabyte
        }
    }
}
