What is the role of event sourcing in the context of Kafka?
What is the role of event sourcing in the context of Kafka?
- Event sourcing utilizes Kafka to define the data schema for events.
- Event sourcing uses Kafka as a message broker for inter-service communication.
- Event sourcing uses Kafka for handling data transformation and aggregation tasks.
- Event sourcing relies on Kafka to store a log of events that can be used to reconstruct the history of an application's state. (correct)

Study Notes
Apache Kafka Use Cases
-
Message Broker Replacement: Kafka provides better throughput, partitioning, replication, and fault tolerance compared to traditional message brokers, making it suitable for large-scale message processing. While traditional brokers may have lower throughput but need low latency, Kafka offers guaranteed durability.
-
Real-time User Activity Tracking: Kafka enables real-time publishing and subscribing to user activity (page views, searches, etc.) on separate topics. This allows for real-time processing, monitoring, and offline data warehousing. High volume of activity messages is typical.
-
Operational Monitoring: Kafka aggregates statistics from distributed applications to create centralized operational data feeds. This replaces log aggregation solutions that collect physical log files from servers.
-
Log Aggregation Replacement: Kafka abstracts away log file details, presenting data as a message stream for easier support of multiple data sources and distributed consumption. It gives better performance, durability, and lower latency than log-centric systems like Scribe or Flume.
-
Data Processing Pipelines: Kafka facilitates processing pipelines with multiple stages, consuming raw input data, aggregating, enriching, or transforming it, and publishing new topics for more processing. Examples include news article recommendation systems.
-
Stream Processing: Kafka Streams is a library for processing and analyzing data in Kafka, supporting concepts like event time, processing time, windowing, exactly-once processing, and state management. Scaling is simple.
-
Event Sourcing: Kafka's large log data storage makes it excellent for event sourcing, where state changes are logged as a sequence of records. Kafka can serve as an external commit log, helping with node replication and failure recovery. This is similar to the Apache BookKeeper project.
-
External Integration: Numerous tools and integrations exist outside of the core Kafka distribution, in areas like stream processing, Hadoop, monitoring, and deployment.
