Implement a custom NestedSet-like data structure to represent transitive header information. There are certain properties that make a slightly different approach more effective: - There is exactly one entry at every node in the DAG - The largest deps represents >90% of the transitive deps (as per experiments) Thus, reusing the memoization of the largest dep substantially reduces CPU and memory consumption. RELNOTES: None. PiperOrigin-RevId: 351377359
{Fast, Correct} - Choose two
Build and test software of any size, quickly and reliably.
Speed up your builds and tests: Bazel rebuilds only what is necessary. With advanced local and distributed caching, optimized dependency analysis and parallel execution, you get fast and incremental builds.
One tool, multiple languages: Build and test Java, C++, Android, iOS, Go, and a wide variety of other language platforms. Bazel runs on Windows, macOS, and Linux.
Scalable: Bazel helps you scale your organization, codebase, and continuous integration solution. It handles codebases of any size, in multiple repositories or a huge monorepo.
Extensible to your needs: Easily add support for new languages and platforms with Bazel's familiar extension language. Share and re-use language rules written by the growing Bazel community.
