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 The Apache Incubator podling was retired on 2023-01-18 and the project is no longer actively maintained.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
