Recommended
5/5

"Apache Kafka is the distributed event streaming platform for APAC data engineering — high-throughput log compaction, consumer groups, and replay for real-time data pipelines. Best for APAC organisations building event-driven architectures with millions of events per second."

What it does

Key features

  • Log-based storage — append-only partitioned log with configurable retention and infinite replay capability
  • Consumer groups — horizontally scalable event consumption with independent offset tracking per group
  • Kafka Connect — 200+ source and sink connectors for APAC data pipeline integration
  • Kafka Streams — stateful stream processing (joins, windows, aggregations) on Kafka topics
  • Replication — configurable partition replication across APAC brokers for fault tolerance
  • Compaction — topic compaction that retains the latest value per key for APAC materialised view use cases
  • KRaft mode — ZooKeeper-free Kafka metadata management (production-ready since Kafka 3.3)
When to reach for it

Best for

  • APAC data engineering teams building real-time event pipelines with multiple independent consumers
  • Event sourcing and CQRS architectures where APAC systems need replay capability and audit history
  • High-throughput APAC applications (millions of events per second) where RabbitMQ throughput is insufficient
  • APAC organisations implementing Change Data Capture from transactional databases to downstream analytics systems
Don't get burned

Limitations to know

  • ! Kafka operational complexity — partition management, replication factor tuning, and consumer group monitoring require dedicated platform engineering expertise in APAC teams
  • ! Kafka is not designed for per-message routing complexity — RabbitMQ exchange routing is more flexible for APAC routing requirements
  • ! ZooKeeper dependency (pre-KRaft) added operational overhead — APAC teams should deploy KRaft-mode Kafka 3.3+ for new deployments
  • ! Managed Kafka options (Confluent Cloud, AWS MSK) reduce operational overhead at the cost of significant licensing or usage fees for APAC production clusters
Context

About Apache Kafka

Apache Kafka is a distributed event streaming platform originally developed at LinkedIn that provides APAC data engineering and platform teams with high-throughput, low-latency, fault-tolerant message streaming — where events are stored in an append-only, replicated log with configurable retention, enabling consumers to read events from any position in the log and replay event history on demand.

Kafka's log-based storage model — where events are durably stored in topic partitions as an ordered, append-only log rather than consumed and deleted as in traditional message queues — is the architectural distinction that makes Kafka suited for event sourcing, event replay, and building multiple independent consumer systems from a single event stream. An APAC financial services event stream (payment authorisations, transaction events) written to Kafka can be consumed simultaneously by a real-time fraud detection system, an analytics aggregation pipeline, an audit log archiver, and a customer notification service — each reading independently from the same event log at its own pace.

Kafka's consumer groups — which enable multiple consumers to share the work of consuming a partitioned topic (each partition is consumed by exactly one consumer in the group at a time), with consumer group offset tracking that enables fault-tolerant at-least-once event processing — provide APAC data engineering teams with horizontally scalable event consumption. Adding more consumers to a Kafka consumer group scales throughput linearly up to the number of topic partitions.

Kafka's Connect framework — which provides a standardised integration layer for streaming data between Kafka and external systems (MySQL databases via Debezium CDC, Elasticsearch, S3, Snowflake, MongoDB, and 200+ connectors) — enables APAC data engineering teams to build event-driven data pipelines by connecting source systems to Kafka and Kafka to destination systems without writing custom integration code.

Kafka Streams and ksqlDB — which enable stateful stream processing (joining, windowing, aggregating, filtering) on Kafka topic data directly within the Kafka ecosystem — provide APAC engineering teams with real-time stream processing without introducing a separate stream processing engine (Flink or Spark Streaming) for simple-to-moderate processing requirements.
