Apache Kafka
Business Profile
Core Value Proposition
Apache Kafka provides a distributed streaming platform for real-time data streaming.
Target Customer
Software engineers, data engineers, and system architects building real-time data pipelines and event-driven architectures.
Key Differentiator
Log-based architecture with topics and partitions, durable replicated storage, leader-based replication, and built-in ecosystem (Kafka Connect and Kafka Streams); evolving consensus (KRaft) to remove ZooKeeper; Tiered Storage to offload history to object stores.
Implementation Timeline
Not explicitly specified for customers; production-ready KRaft version debuted in Kafka 3.3 (October 2022); ZooKeeper removal planned for Kafka 4.0 (expected around Q3 2024).
Pain Points
- 1Need for real-time, high-throughput data streaming at scale (millions of messages per second).
- 2Desire to decouple producers and consumers to avoid backpressure and improve resilience.
- 3Requirement for durable, fault-tolerant storage with scalable data management across clusters.
Key Features
- 1Topics and logs as the fundamental storage unit for streaming data.
- 2Partitioning and replication for scalability and durability.
- 3Producers with configurable acks (acks=0, 1, all) and consumer groups with offset tracking (__consumer_offsets).
- 4Kafka Connect for integrating Kafka with external systems (sources and sinks) via connectors.
- 5Kafka Streams for in-application real-time stream processing; built-in exactly-once processing semantics in some scenarios.
- 6Tiered Storage to store most data in a remote object store (e.g., S3) while keeping hot data locally for performance.
- 7KRaft (Kafka Raft) consensus mode to replace ZooKeeper; combined/isolated deployment options; metadata handling via a dedicated topic.
Target Customer Industries
Decision Makers
- 1Apache Kafka Committer
- 2Senior Director of Engineering
- 3Editor
Client Results
- 1Capable of millions of messages per second throughput and storing terabytes of data (as described in the content).
- 2Development tests reported a 43% producer performance improvement when historical consumers were present with Tiered Storage.
Competitive Advantages
- 1High-throughput, scalable streaming with durable, replicated storage.
- 2Decouples producers and consumers, enabling independent scaling and resilience.
- 3Rich ecosystem including Kafka Connect for data integration and Kafka Streams for in-app processing.
- 4Partitioned architecture enables parallelism and scalable reads/writes.
- 5Tiered Storage reduces I/O pressure by offloading historical data to object stores.
- 6Evolving consensus model (KRaft) to simplify metadata management and remove dependency on ZooKeeper.

Additional Product Information
Product Description
A distributed streaming platform designed to store and process real-time data via a durable, log-based architecture. It uses topics, partitions, and replication to enable high-throughput, fault-tolerant streaming, with integrated tools like Kafka Connect and Kafka Streams and capabilities like Tiered Storage.
Target Market
Organizations and engineering teams needing real-time data pipelines, event-driven architectures, and scalable data processing.
Unique Value Proposition
Kafka acts as the central nervous system for an organization’s data, providing real-time streaming, durable storage, decoupled producers/consumers, and a comprehensive ecosystem to ingest, process, and move data at scale.
Technical Requirements
Operates over TCP using the Kafka protocol; relies on a broker-based cluster with topics, partitions, and replicas; supports producer acks configuration and consumer groups with offset tracking; uses ZooKeeper historically and now moving to KRaft; includes a metadata topic for cluster state; Tiered Storage integrates with object stores (e.g., S3).
Pricing Model
Not specified in content; Kafka is discussed within an open-source context (references to Apache open-source projects).
