BIY Workflow with FastAPI, Python and Skipper

Build It Yourself. In this video, I explain how you can build workflow running with FastAPI REST generic endpoints.

I explain how workflow call is integrated into FastAPI logic and how the call is made to get the queue name from the workflow. Using this queue name and RabbitMQ message broker, event-based communication runs between containers.

TensorFlow Decision Forests Example

With TensorFlow Decision Forests we can handle structured data without much preprocessing. There is no need to normalize numeric values, one-hot encode categorical values, or set magic values to replace missing data. I give it a try and run this new feature of TensorFlow in this video. The demo is based on the Titanic dataset taken from Kaggle.

FastAPI Background Tasks for Non-Blocking Endpoints

With FastAPI it is super easy to implement a non-blocking endpoint. This is useful when the endpoint calls logic, which should be executed asynchronously and you don't need to wait for the result, but want to return a response immediately. For example - a service that does logging. We don't want to wait until the log will be written but return the response instantly.
