The extension adds Operators to design and deploy streaming analytic process on Flink or Spark.

This is a beta version. Please use it carefully, as features are still under development.

The streaming analytic process is designed inside the Streaming Nest operator. Processes are deployed by creating and providing a connection object to the corresponding cluster.

Processes designed are platform independent. They can be deployed on other platforms (changing also from Flink to Spark and vise-versa) by just changing the provided connection object.

Deployed streaming jobs can be monitored and managed by using the Streaming Dashboard, which can be enabled over the View -> Show Panel menu.

The extension provides the following Operators:

  • Streaming

    • Input Output

      • Kafka Sink

      • Kafka Source

    • Flow Control

      • Duplicate Stream

      • Join Streams

      • Connect Streams

      • Union Stream

    • Transformations

Version 0.6.1 (2022-02-07)

  • Added checks for the topic name parameter of the Kafka Source and Sink operators
    • The topic name is checked for invalid and/or colliding characters. Quickfixes are provided to replace these with underscores.
    • A user error is thrown in case a topic name contains invalid characters
  • Added the "Early Time-Series Classification Engine" operator to integrate the partner service from the INFORE project to deploy and use the early time-series classification engine of the partner in streaming workflows.
  • Bugfix for the integration of the Benchmarking component of the INFORE Optimizer service.
  • Bugfixes for the Streaming Optimization Operator for the communications with the INFORE Optimizer service.

  • Plug-Ins for deploying RM models on Flink and Spark clusters are shipped with the extension
  • Connectivity checks for Flink and Spark Connections are now possible
  • Stopping process deployment now works
  • Added a User Error, in case no stream processing operators are added in the Streaming Nest operator.
  • Restructured operator groups
  • Add a new Maritime Akka Cluster connection object class to store the ip address (and any other necessary information ) and be used by the Maritime Event Detection operator
  • Maritime Event Detection operator now differentiate between job types (events & fusion)

Version 0.5.0 (2021-10-21)
