Fun write-up. Good stuff, very nice contribution to to compio of compio-ws. Looks like the Iggy switched to thread-per-core compio back in July. https://github.com/apache/iggy/pull/1960

One thing I saw mentioned in the 0.5.0 release notes (which happened shortly after migrating to compio): trying to switch to a Sans-IO model design (but maybe just for clients?). It feels like there's similar ownership concerns that might arise, as seen here with the poll-vs-completion challenges faced here. A lot of good learnings to be had, as we go forth to faster better io, eager to keep tuning in & hearing more. Thanks for the write up! https://iggy.apache.org/blogs/2025/08/10/release-0.5.0/#what... https://www.firezone.dev/blog/sans-io

Thanks! Actually, the mentioned PR was just an internal merge; the one to the master branch is this one https://github.com/apache/iggy/pull/2299 which happened last week :)

Sans-IO is for clients only, and we'd like to introduce it one day to SDK to support the different runtimes as well as the blocking, sync client.
