Sylph Build Status

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

  • Spark-Streaming (Spark1.x)
  • Structured-Streaming (Spark2.x)
  • Flink Streaming

Building

sylph builds use Gradle and requires Java 8.

# Build and install distributions
./gradlew clean assemble

Running Sylph in your IDE

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:

  • Open the File menu and select Project Structure
  • In the SDKs section, ensure that a 1.8 JDK is selected (create one if none exist)
  • In the Project section, ensure the Project language level is set to 8.0 as Sylph makes use of several Java 8 language features
  • HADOOP_HOME(2.6.x+) SPARK_HOME(2.4.x+) FLINK_HOME(1.7.x+)

Sylph comes with sample configuration that should work out-of-the-box for development. Use the following options to create a run configuration:

  • Main Class: ideal.sylph.main.SylphMaster
  • VM Options: -Dconfig=etc/sylph/sylph.properties -Dlogging.config=etc/sylph/logback.xml
  • ENV Options: FLINK_HOME= HADOOP_CONF_DIR=$HADOOP_HOME/etc/hadoop
  • Working directory: sylph-dist/build
  • Use classpath of module: sylph-main
