# Remote Execution API

The Remote Execution API is an API that, at its most general, allows clients to
request execution of binaries on a remote system. It is intended primarily for
use by build systems, such as [Bazel](bazel.build), to distribute build and test
actions through a worker pool, and also provide a central cache of build
results. This allows builds to execute faster, both by reusing results already
built by other clients and by allowing many actions to be executed in parallel,
in excess of the resource limits of the machine running the build.

## Dependencies

The APIs in this repository refer to several general-purpose APIs published by
Google in the [Google APIs
repository](https://github.com/googleapis/googleapis). You will need to refer to
packages from that repository in order to generate code using this API. If you
build the repository using the included `BUILD` files, Bazel will fetch the
protobuf compiler and googleapis automatically.

## Using the APIs

The repository contains `BUILD` files to build the protobuf library with
[Bazel](https://bazel.build/). If you wish to use them with your own project in
Bazel, you will possibly want to declare `cc_proto_library`,
`java_proto_library`, etc. rules that depend on them.

Other build systems will have to run protoc on the protobuf files, and link in
the googleapis and well-known proto types, manually.
