How Python Data Engineers Use Nakadi

Python data engineers use Nakadi's HTTP API via the `nakadi-client` Python library to publish domain events from Python microservices without managing Kafka producers directly. The subscription API provides a long-polling endpoint that Python consumers call to receive events in order — with Nakadi managing offset tracking automatically rather than requiring consumer group configuration.
