    * Although it's probably not very problematic here with the way `SQLAlchemy` works.
    * But if you added more code to the middleware that had a lot of <abbr title="input and output">I/O</abbr> waiting, it could then be problematic.
* A middleware is run for *every* request.
    * So, a connection will be created for every request.

# Dependencies

**FastAPI** has a very powerful but intuitive **<abbr title="also known as components, resources, providers, services, injectables">Dependency Injection</abbr>** system.

It is designed to be very simple to use, and to make it very easy for any developer to integrate other components with **FastAPI**.

## What is "Dependency Injection"

// Insert a "requant" op after the mean op if the mean has different scales for
// input & output.
// Please note: THIS IS NOT a mathmetically-equivalent transformation and it may
// loose accuracy, so we need to use this very very carefully.

    TFL::MeanOp mean_op, PatternRewriter& rewriter) const {
  auto input = mean_op.getInput();
