S3 Storage Alternatives

AWS S3 is the defacto standard for object storage. Therefore there are many alternatives that implement the same API, but based on disk or other storages.

• MinIO
  • OpenMaxIO: Forked UI for MinIO Object Storage
• Garage
• Ceph.io — Home
• Zenko Zenko is the open source multi-cloud data controller: own and keep control of your data on any cloud.
• SeaweedFS: is a fast distributed storage system for blobs, objects, files, and data lake, for billions of files! Blob store has O(1) disk seek, cloud tiering. Filer supports Cloud Drive, cross-DC active-active replication, Kubernetes, POSIX FUSE mount, S3 API, S3 Gateway, Hadoop, WebDAV, encryption, Erasure Coding.
• DuckDB DiskCache: Supports a “fake-S3” fake_s3://X filesystem which acts like S3 but directs to the local filesystem, while adding fake network latencies similar to S3 latencies (best-case “inside the same AZ”). This is a handy tool for local performance debugging without having to spin up an EC2 instance. One could e.g. create a SF100 tpch database and generate parquet files e.g., using:

1
2
3

load tpch;
call dbgen(sf=100);
copy (from lineitem) to 'sf100' (FORMAT parquet, file_size_bytes '20MB', filename_pattern 'limeitem_{i}', overwrite_or_ignore 1);
