Event Streaming

Event streaming is the continuous capture and transmission of events - discrete records of things that happened, such as a price change, a new property listing, or a user search - as an ordered, persistent log that multiple consumers can read from at their own pace.

Apache Kafka is the dominant event streaming platform. Events are written to topics (named log partitions), and any number of consumer services can subscribe to a topic and process events independently. This decouples producers from consumers - a price change event can simultaneously update a database, trigger a user alert, and refresh a dashboard.

Event streaming enables event-driven architectures where services react to data changes in real time. For data-intensive applications - live price tracking, real-time market monitoring, or property alert systems - event streaming provides the infrastructure layer that connects data sources to multiple downstream consumers with minimal latency.
