GC reduction: convertStarlarkArgumentsToJavaMethodArguments - use ArrayList instead of ImmutableList.Builder This reduces the number of copies by one, because ImmutableList.Builder.build makes a copy, and toArray makes another copy, whereas with ArrayList the first copy goes away (the second still applies). - use CompactHashSet instead of LinkedHashSet - avoid creating a new Set if it's going to be empty note that CompactHashSet actually _increases_ memory consumption for empty sets, so we need to make sure that we don't do that On a benchmark, this reduces memory allocation by this method by a factor of more than 2.

Speed up your builds and tests: Bazel only rebuilds 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.
