I have set up Seafile with an s3 compatible backend and everything works great, but I have noticed something really weird: the 3 MySQL databases are really tiny, with few rows each. The actual files are stored in s3 buckets, but where is the metadata stored? I would doubt that it fetches the list of files and directories from s3 because it would be very slow - there are hundreds of thousands of files - yet Seafile is super fast at showing the files and directories. What am I missing? Thanks!

handling and versioning. Only the Library ID is stored the the Database. Any othe information is stored in the Storage. Take a look on the following Picture:
