Generics and Compile-Time in Rust
This is the second episode of the Rust Compile Time series. Brian Anderson, one of Rust's original authors, talks about monomorphization, using the TiKV project as a case study.
How We Improved TPC-C Performance by 50% and TPC-H Performance by 100%
TiDB 4.0 release greatly outperforms TiDB 3.0. Our TPC-C benchmark improved by about 50% and our TPC-H benchmark improved by about 100%.
Quickly Find Rust Program Bottlenecks Online Using a Go Tool
It can be hard to find Rust programs' performance bottlenecks online. By integrating pprof-rs in TiKV, we can use the Go tool pprof to visualize TiKV's profiling data. This helps analyze the program's performance online.
