In its own words
The project's README opens: "One weed binary serves an S3 object store, a POSIX file system, and a lakehouse with S3 Tables, all over the same data. Each blob is one disk read away, capacity grows by starting another volume server, and cloud storage can be cached or tiered transparently. Both read and write operations have O(1) complexity and can run at the full speed supported by the underlying hardware."
