TiDB Weekly

News & blog post

One of the fundamental tradeoffs of programming language design is run-time performance vs. compile-time performance. The Rust team nearly always (if not always) chose run-time over compile-time.

Last week, we published a post that discusses the following topics as the first episode in a series of posts:

  • The spectre of poor Rust compile times at PingCAP
  • The TiKV compile-time adventure so far
  • Rust's designs for poor compilation time
    • Bootstrapping Rust
    • (Un)virtuous cycles
    • Early decisions that favored run-time over compile-time
  • Recent work on Rust compile times
