I use the same stack to run my apps! sqlite as Database backen on ephemeral pods. On initialisation, the pod restores the current litestream backup from object storage. No persistent volumes needed. No issues so far.
Without persistent volumes, every deployment of the app may require the SQLite data to be restored from S3, which can take time if database size is large. With PVC, regular app deployments use existing database, only a disaster recovery scenario restores from S3.
Yes, it feels magical to just recreate your namespace or even create a new K8s cluster and see all your apps (from OpenRun metadata) and app data restored automatically.
It's classic HN to criticize OP that their solution doesn't scale, and then for OP to respond by saying that they don't need the scale and anyway PG tells you to do things that don't scale.
SQLite is great for small-production scale. Don't let anyone tell you different. Just keep in mind that it's a pain to move if you ever do need to scale up. If it's a startup, you might. If it's a weekend hobby project you're building for your personal use only, you probably won't.
