I have a library of videos that I’ve downloaded with whisparr running in a docker container. I’ve had a problem with the sqlite DB getting corrupted on a daily basis. I followed the guide on switching to postgres and it only took about 15 minutes, including setting up a postgres server. I really recommend anyone running it to do that. There’s been a noticeable performance boost too.
I had trouble with the sqlite databases when I was writing them to a remote volume over nfs. I’ve had zero issues since moving them to local disk and performance is great.
