Pipeline Log
Description
Allows to log the activity of a pipeline with another pipeline.
A pipeline log streams logging information from a running pipeline to another pipeline.
The only requirement for the receiving pipeline is that it starts with a Pipeline Logging transform. Other than that, the logging pipeline is "just another pipeline". In this logging pipeline, you can process the logging information and e.g. write to a relational or NoSQL database, a Kafka topic etc
Samples
The samples project comes with an example pipeline log.
Check the metadata perspective for the pipeline log pipeline-log-example. This pipeline log is configured to send logging information for the pipeline ${PROJECT_HOME}/reflection/generate-fake-books.hpl to the logging pipeline ${PROJECT_HOME}/reflection/pipeline-log-example.hpl.
