Release Notes for GoldenGate Stream Analytics

1.1.1.11.1 Advanced Pipeline

A pipeline defines the pipeline logic and is a sequence of data processing stages. A stage can be one of the following types – Query, Pattern, Rule, Query Group, Custom, and Scoring. A pipeline starts with a stream stage and can have one or more children of any type such as Query, Rule Pattern etc.

Oracle Stream analytics 19.1 introduces advanced pipeline features like splitting a pipeline into multiple branches at any stage as per your application logic. You can end each branch with one or more targets. It provides enhanced editing capabilities like editing intermediate stages and the changes due to that are propagated to downstream stages. You can now edit the sources even if those are already being used in any pipelines. With a pipeline, you can switch the streams in the source and will be notified of the corrective actions you will need to accommodate the change in source. You can now also use output of an existing stage as one of the source for another stage in the pipeline.

Oracle Stream Analytics 19.1 now supports the operation on all types of artifacts including Visualizations, Cubes, Dashboards, Scoring Stage and Custom Stage. When you import and export, any custom jar that you use in the pipeline is also taken care during the operation. It allows you to review the export bundle, edit names and description of artifacts and manage the tags during the export. During import, it allows you to inspect the import bundle, select items to import and manage tags at the time of import.
