The early design decisions for the Categorical type were under strain because of our streaming engine. Every data chunk carried its own mapping between the categories and their underlying physical values, forcing constant re-encoding. The global StringCache we built to solve it caused lock contention and wasn't designed for a distributed architecture. The new Categories object, released in 1.31, solves this, and gives you: • Control over the physical type (UInt8/16/32) • Named categories with namespaces • Parallel updates without locks • Automatic garbage collection When you know the categories up front you can use Enums. They're faster because of their immutability and allow you to define the sorting order of values. The StringCache is now a no-op, but the code will keep working how it used to (with global Categories). You can also migrate by replacing it with explicit Categories where needed. The result is a Categoricals data type that works well on the streaming engine without performance degradation, and is compatible with a distributed architecture.

I've written a blog about Tonbo's research on async Rust and io_uring： tonbo.io/blog/async-rus… We need to be careful to avoid the cancellation problem when using async Rust and io_uring together.
