> [@crepererum](https://github.com/crepererum) pointed out recently that there is a Rust blog post about the new solver in the Rust compiler (and it mentions that datafusion specifically as something that gets 10x faster with the new solver): > > https://blog.rust-lang.org/2026/08/21/enabling-next-solver-on-nightly/ > > I am not sure if this will be in addition to what [@Dandandan](https://github.com/Dandandan) did in [#13814 (comment)](https://github.com/apache/datafusion/issues/13814#issuecomment-5292709677), but it is pretty cool to see the shoutout Yes - it is the same issue, so this will probably no longer give any speed up - in fact I measured compilation to be a bit slower in the next gen trait solver (I guess it probably will be optimized a bit further before stabilization). - 10x (or 4x in the linked article) refers to optimizing the new solver (which was slower than the old one first), also it probably `cargo check` or something on that module only (i.e. not all dependent crates). The 10x happens to correspond with https://github.com/apache/datafusion/pull/24329 as well. - I traced the issues in the old trait solver: https://github.com/rust-lang/rust/issues/157595#issuecomment-5312290980 -- This is an automated message from the Apache Git Service.
