Improve project charter

[romusz]

Hello there,

Happy to see Rust community getting into Iceberg.
To help deciding between Icelake, iceberg-rust, and Iceberg-rs, would you mind clarifying how those 3 differ:

• would your project provide just a reader and writer of Iceberg files (manifest, manifest lists, metadata) or also include integrations with processing and query engines? If so, which ones are considered?
• is implementation of Iceberg REST catalog in scope for your project?

Thanks a lot!

To help deciding between Icelake, iceberg-rust, and Iceberg-rs, would you mind clarifying how those 3 differ:

All contributors from icelake and iceberg-rs have united under iceberg-rust. Our shared objective is to develop Iceberg Rust upstream. Ultimately, we aim to integrate all existing features of icelake into iceberg-rust.

would your project provide just a reader and writer of Iceberg files (manifest, manifest lists, metadata) or also include integrations with processing and query engines? If so, which ones are considered?

For now, we only have reader and writer support. And in the future, we might provide native datafusion support.

is implementation of Iceberg REST catalog in scope for your project?

Yes, of course. We have implemented REST catalog both in icelake and iceberg-rust.

We recommand you take a look over iceberg-rust first. We are working on iceberg-rust's first release. Welcome to join the development!
