A bunch of small changes to prepare SkyQueryEnvironment for full-parallel evaluation:
-Rename QueryExpression#evalConcurrently to QueryExpression#parEval. (parallelism is not concurrency! See https://existentialtype.wordpress.com/2011/03/17/parallelism-is-not-concurrency/)
-Have SkyQueryEnvironment#eval (used recursively in #evaluateQuery) dynamically call QueryExpression#parEval when appropriate.
-Delete QueryExpression#canEvalConcurrently.
-Add ThreadSafety annotations in a bunch of relevant places in the query codebase.
-A bunch of testing infrastructure to test parallel query evaluation.
-TODOs for implementing parallel evaluation of all QueryExpression nodes.

Bazel (Beta)

{Fast, Correct} - Choose two

Bazel is a build tool that builds code quickly and reliably. It is used to build the majority of Google‘s software, and thus it has been designed to handle build problems present in Google’s development environment, including:

  • A massive, shared code repository, in which all software is built from source. Bazel has been built for speed, using both caching and parallelism to achieve this. Bazel is critical to Google's ability to continue to scale its software development practices as the company grows.

  • An emphasis on automated testing and releases. Bazel has been built for correctness and reproducibility, meaning that a build performed on a continuous build machine or in a release pipeline will generate bitwise-identical outputs to those generated on a developer's machine.

  • Language and platform diversity. Bazel's architecture is general enough to support many different programming languages within Google, and can be used to build both client and server software targeting multiple architectures from the same underlying codebase.
