    Kafka Connector for publishing data from Kafka to Ably

    Publishing Kafka records to Ably is easily achieved by using the Ably Kafka Connector, a sink connector that can be self-hosted, or hosted with a third-party provider - the most common being the Confluent Platform.

    Let's start by generating some conferences! We can do this by using the generation script called, which you can find in the testing folder. The script creates a defined set of JSON payloads - these are events (conferences) that start from the current date. All of them have random names and ticket numbers. The conferences are offset through time to make it a bit easier to see the streaming window in action.

    I hope this guide serves as a helpful description and walkthrough of building a dependable realtime ticket booking solution. Next, you can dive into the GitHub repository. You might also want to check out Ably Labs on GitHub, for more examples of what you can do with Ably.

  • GitHub repo uvicorn

    The lightning-fast ASGI server. 🦄

    FastAPI requires an Asynchronous Server Gateway Interface (ASGI) server to power it. Popular choices include Uvicorn, Gunicorn, and Hypercorn. In production, it's probably worth using Hypercorn,  which comes with HTTP/2 support, increasing performance (this is especially useful for outbound webhooks received from Ably). However, for this demo we are going to use Uvicorn, since it has a friendly debugging setup.

  • GitHub repo starlette

    The little ASGI framework that shines. 🌟

    FastAPI is built on top of two key libraries: Starlette and Pydantic. Starlette was developed by one of the creators of the Django REST framework in an attempt to simplify and speed up the process of building REST APIs in Python. Starlette is fast and asynchronous by design, giving FastAPI runtime speed, and a simple, extensible foundation.

  • GitHub repo pydantic

    Data parsing and validation using Python type hints

    API and data definition specifications allow developers to easily build services that can communicate with each other reliably, and validate data. For our REST API component (FastAPI), this means using an OpenAPI Specification (Swagger), with a JSON schema. The REST API uses Pydantic to provide the information needed to create the OpenAPI Specification and generate the functions required to validate and deserialize the inbound data.

  • GitHub repo fastapi

    FastAPI framework, high performance, easy to learn, fast to code, ready for production

    FastAPI is a high-performance, highly-structured web framework for developing web APIs with Python, based on standard Python type hints. It's built on top of Starlette and Pydantic, and it enables us to use a REST interface to validate, serialize, and deserialize data. We'll use FastAPI to build our frontend API component, which is responsible for writing to Kafka topics, and consuming webhooks from Ably.

  • Scout APM

    Less time debugging, more time building. Scout APM allows you to find and fix performance issues with no hassle. Now with error monitoring and external services monitoring, Scout is a developer's best friend when it comes to application development.
