of all source files and build targets, Buck can perform incremental recompilation, only rebuilding targets downstream of files that have changed. Buck computes a key for each target that is a hash of the contents of the files it depends on. It stores a mapping from that key to the build target in a build cache. If targets are deterministic functions of the contents of their dependencies, then this build cache can be shared between developers and continuous integration (CI) as Buck supports
