Stage
A Stage, also called a Stage Node, sits between sources and final marts. Use Stage Nodes to cleanse, join, or reshape data before Dimension or Fact Nodes.
By default, Stage Nodes truncate and reload on each run so the table mirrors the current source batch. You can change load behavior with Node options such as Truncate Before or incremental strategies from Packages.
Stage Nodes are a common first custom layer after Source Nodes in new pipelines.
See Nodes and Node Types for Stage behavior and alternatives.
