squirrel VS seaweedfs

I built https://github.com/anacrolix/squirrel for just this purpose. However you might find that batch inserting empty files might only be 10x faster or so than creating empty files directly on the filesystem if we are to believe the 10k/s the OP achieved.

I'm looking for an embedded database/KV-store that supports a write-heavy workload of large blocks of bytes and some kind of eviction policy. I'm currently using sqlite3 with a bunch of triggers and the blob API, but it's not really suitable for write-heavy workloads. I've currently exposed the interface somewhat in https://github.com/anacrolix/squirrel, the primary use case is from https://github.com/anacrolix/torrent. My recent research suggests an LSM-based KV-store like rocksdb or leveldb, but those don't have great interfaces in Go, and don't seem to support an eviction policy as far as I can tell (which is surprising given they would be very well suited to it). There are some alternatives like buntdb, but those all look designed for smaller/string values.

Whoops: WebDAV:

SeaweedFS supports WebDAV. https://github.com/seaweedfs/seaweedfs/wiki/WebDAV

I'm not able to find if both/restic supports mounting backups as WebDAV, but in theory there's nothing stopping you.

It's 100% user space (expose a rest service) and supported by a bunch of file-browsers with a bit of a network aware component to it as well.

If you want/need to take out the metadata, there's some nice solutions for that https://github.com/seaweedfs/seaweedfs

I posted this on https://github.com/seaweedfs/seaweedfs/discussions/5290

I like the idea of using SeaweedFS as an intermediate layer with object write notifications going to SQS, RabbitMQ, or a local file, which could also allow me to observe the changes to different files through a metric collection layer like Prometheus and Grafana.

> Theoretically they could swap with minio but last time we used it it was not a drop-in replacement yet.

Depends on whether AGPL v3 works for you or not (or whether you decide to pay them), I guess: https://min.io/pricing

I've actually been looking for more open alternatives, but haven't found much.

Zenko CloudServer seemed to be somewhat promising, but doesn't seem to be managed very actively: https://github.com/scality/cloudserver/issues/4986 (their Docker images on DockerHub were last updated 10 months ago, which is what the homepage links to; blog doesn't seem active since 2019, forums don't have much going on, despite some action on GitHub still)

There was also Garage, but that one is also AGPL v3: https://garagehq.deuxfleurs.fr/

The closest I got was discovering that SeaweedFS has an S3 compatible mode: https://github.com/seaweedfs/seaweedfs
