Bazel in Practice: Migrating a Multi-Language HFT Monorepo || C++ MeetUP

​Who we Are?

​🟢 Pinely is a privately owned and funded algorithmic trading firm with offices in the Netherlands, Singapore, and Cyprus.
We specialize in high-frequency and ultra-low-latency trading, where every microsecond counts.

​Abstract: fast, reliable and extensible build system is critical for ecosystems with multiple compiled languages and containers deployment.
With default build systems for languages like Go and Rust, custom build and packaging scripts for container images and Python, and Cmake being the only somewhat extensible build system, realistically only suitable for C++, we needed a better tool for our monorepo.
In this talk, I'll share what this actually looks like in practice -- including things that worked, things that didn't, and things we're still figuring out.

​1. Quick overview of CI and releases before Bazel migration
2. All the quirks we used to make CMake usable (always-link libs, conan, extensions)
3. Why bazel, what is Bazel, Bazel 101
4. Long migration from CMake
5. Relatively quick migrations for Go and Rust, and why
6. Building container images without Docker
7. Remote cache and build and their problems
8. What we achieved so far
9. What old/new problems do we have now
