## Decision

The *Build Tool Team* has decided to use Architectural Decision Records (aka ADR) to track decisions we want to follow.

        SessionBuilder session = new MavenSessionBuilderSupplier(system).get();
        session.withLocalRepositories(new LocalRepository(new File("target/local-repo"), "simple"));
        session.setTransferListener(new ConsoleTransferListener());
        session.setRepositoryListener(new ConsoleRepositoryListener());

        return session.build();
    }

    * Will have the next best performance, after Uvicorn. In fact, Starlette uses Uvicorn to run. So, it probably can only get "slower" than Uvicorn by having to execute more code.
    * But it provides you the tools to build simple web applications, with routing based on paths, etc.
    * If you are comparing Starlette, compare it against Sanic, Flask, Django, etc. Web frameworks (or microframeworks).
