You made the claim:

what makes it different is a new way of programming for the cloud era.

but you aren't even explaining how anything is different from what a normal file system can do, let alone what makes it a "new way of programming for the cloud era".

Sorry it was not so clear. Previously fallocate just allocate disk space for a local server. Now SeaweeedFS can allocate a blob on a remote storage.

What is the difference between a blob and a file and what is the difference between allocating a blob on remote storage or a file on remote storage?

[chrislusf]

A large file can be chunked into blobs.

Sorry, everybody has different background of knowledge. Hard to understand where the question comes from. I think https://www.usenix.org/system/files/fast21-pan.pdf may be helpful here.

They were straightforward questions. The paper you linked talks about blobs as a term for appending to files. Mostly it seems to be about wrapping and replicating XFS.

Is that why you are avoiding talking about specifics? Are you wrapping XFS?

I'm little confused why people are being so weird with the OP, asking what the difference between a blob and a file aren't something for seaweedfs lol, Blobs and Files, and other terms are terms used to describe different layers of data allocation in almost every modern object storage solution.

Blobs are what lie under files, you can have a file split into multiple blobs spread across different drives, or different servers etc, and then can put it back together into a file when requested, thats how i understand it at a basic level

> Why does a user need that? Filesystems already break up files into blocks / sectors. Why wouldn't a user just deal with files and let the filesystem handle it?

A blob has its own storage, which can be replicated to other hosts in case current host is not available. It can scale up independently of the file metadata.

I really don't understand why you aren't eager to explain the differences and what problems are being solved.
