Concept: Dataset Stages
A stage is a pipeline object that takes in data, transforms it in some way, and outputs
modified data. A stage performs a single computational function, such as joining data
with a Join stage or parsing data from the dataset source with a Parse stage.
Prism Analytics supports these stage types:
- Import
- Parse
- Manage Fields
- Filter
- Group by
- Join
- Union
- Unpivot
Adding a stage can change the number of records and fields in the dataset.
Deleting a Union or Join stage disconnects but keeps the stage's pipelines. If
you don't want to keep the disconnected pipelines, delete or use them in another Join or
Union stage in the Primary Pipeline.
You can't delete or add an Import stage or a Parse stage.
