The Sylph is Streaming Job Manager.
Sylph uses SQL Query to describe calculations and bind multiple source(input)/sink(output) to visually develop and deploy streaming applications.
Through Web IDE makes it easy to develop, deploy, monitor streaming applications and analyze streaming application behavior at any time.
Sylph has rich source/sink support and flexible extensions to visually develop and deploy stream analysis applications and visualized streaming application lifecycle management.
The Sylph core is to build distributed applications through workflow descriptions. Support for

sylph builds use Gradle and requires Java 8.
# Build and install distributions ./gradlew clean assemble
After building Sylph for the first time, you can load the project into your IDE and run the server. Me recommend using IntelliJ IDEA.
After opening the project in IntelliJ, double check that the Java SDK is properly configured for the project:
Sylph comes with sample configuration that should work out-of-the-box for development. Use the following options to create a run configuration:
：Code submit frequency
：React/respond to issue & PR etc.
：Well-balanced team members and collaboration
：Recent popularity of project
：Star counts, download counts etc.
