[GitHub] [arrow-rs] tustvold commented on issue #2170: Quite long compilation time

   This is something I would be very interested in improving, but I've not had time to really sit down with this yet.
   
   Two rather crude approaches could be to split up the crate to allow greater build parallelism, or to add more features to allow people to opt-out of functionality.
   
   Similarly messing with increasing the codegen-units might help, although potentially at the cost of less optimal builds.
   
   The major bottleneck last time I looked was linking, and LLVM codegen, which makes it hard to optimise without dropping functionality...
