Anyone using io_uring?

• glommio

  29 2,828 6.8 Rust

  Glommio is a thread-per-core crate that makes writing highly parallel asynchronous applications in a thread-per-core architecture easier for rustaceans.

  

After retbleed, spectre and meltdown mitigations took more than 60% of the performance of our CPUs, we have the opportunity to get a good chunk of that performance back thanks to io_uring. Anyhow I don't see many projects using it yet (Glommio being the big exception).

• rio

  7 894 0.0 Rust

  pure rust io_uring library, built on libc, thread & async friendly, misuse resistant (by spacejam)

for completeness there is also rio, but:

• InfluxDB

• xNVMe

  3 209 9.5 C

  Portable and high-performance libraries and tools for NVMe devices as well as support for traditional/legacy storage devices/interfaces.

  

Basically io_uring grew a lot, the latest API offers incredible tools but there are very few examples in any language (xnvme and fio), and in particular I'm struggling to understand how to do it in Rust: where should unsafe code stop? should I simply expose the io_uring api as unsafe, or should I do more work in C and present the ring when ready to rust?

• tokio-uring

  28 998 4.1 Rust

  An io_uring backed runtime for Rust

  

- Tokio suffers from a similar problem

• fio

  30 4,842 9.3 C

  Flexible I/O Tester
