mountpoint-s3 VS juicefs

... or does "S3 file system" mean https://github.com/awslabs/mountpoint-s3 - a Rust project by AWS Labs that provides "a simple, high-throughput file client for mounting an Amazon S3 bucket as a local file system" ?

Looks like support for S3 Express was merged in with version 1.30 just a few hours ago https://github.com/awslabs/mountpoint-s3/pull/642

mountpoint-s3 is AWS’ first party solution for mounting s3 buckets as file systems: https://github.com/awslabs/mountpoint-s3

Haven’t used it but it looks cool, if a bit immature.

This might be useful with a MinIO server, although not directly supported

Support for Kerberos keytab files

JuiceFS under the Apache License 2.0, is a high-performance POSIX file system optimized for cloud-native environments. It stores data in Object Storage (e.g., Amazon S3) and metadata in databases like Redis, MySQL, or TiKV. JuiceFS integrates massive cloud storage with big data, machine learning, and AI applications efficiently, akin to local storage. It features full POSIX and Hadoop compatibility, S3 interface, Kubernetes support, and shared file storage for numerous clients. Some cool features are - strong consistency, scalable performance, data encryption, global file locks, and compression with LZ4 or Zstandard.

To improve the handling process of capacity overrun, the JuiceFS client supports deletion operations in the case of Ceph cluster fullness (see related code changes in JuiceFS Community Edition). Therefore, for newer client versions, there is no need to use set-full-ratio for temporary adjustments.

The architecture image shows GCS and others, so I suspect it does.

Adds a DBMS or key-value store for metadata, making the filesystem much faster (POSIX, small overwrites don't have to replace a full object in the GCS/S3 backend).

Almost certainly a better solution if you want to turn your object storage into a mountable filesystem, with the (big) caveat that you can't access the files directly in the bucket (they are not stored transparently).

JuiceFS can do the same thing as s3fs-fuse, but better. Because it supports robust data consistency and caching policies to improve performance.
