Apache Heron is a realtime, distributed, fault-tolerant stream processing engine originally developed at Twitter as a successor to Apache Storm. The Apache Incubator podling was retired on 2023-01-18 and the project is no longer actively maintained.

Use cases

  • process realtime event streams at scale
  • run fault-tolerant distributed stream analytics
  • migrate Apache Storm topologies to a faster engine
  • build realtime analytics pipelines for high-throughput data
  • process clickstream or telemetry data in real time

When to choose

  • you already run Heron and need to maintain an existing deployment
  • you need a Storm-compatible topology API with better resource isolation

When to avoid

  • you are starting a new stream processing project - the project was retired from the Apache Incubator in 2023 and is unmaintained
  • you want long-term community support or recent releases
  • you prefer actively developed alternatives like Apache Flink, Kafka Streams, or Spark Structured Streaming
