This directory contains implementations of Heron spouts that can be used in user topologies.
The spout implementations are maintained by Heron community.
Spout implementation files should be organized in this directory structure:
Client name: kafka, pulsar, etc Language: java, python, scala, etc Spout name: kafka_spout, stateful_kafka_spout, etc
Files in each spout should be organized into these subdirectories:
src/main/: source code
src/test/: unit tests
Each spout should have a design doc as well as related information in the doc/ directory.
All source code files should include a short Apache license header at the top.
