What's a reasonable size for the config volume?

[scubbo]

I'm running Jellyfin on Kubernetes via a homemade Helm chart. I recently switched from mounting /config directly from an NFS server, to using a size-constrained democratic-csi-provided volume, which prompted me to realize something surprising - I've repeatedly run into issues where the config volume has filled up and I've had to increase the size of the volume to get the service working again.

With 220 Movies and 116 TV Shows, my config volume is currently using 88% of a 5Gb mount, with 3.8G of that in /config/metadata. Is that a normal usage? If not, where should I look for possible issues?
