FeaturePrioritizer

FeaturePrioritizer

FeaturePrioritizer outputs features in a sorted order according to which Input Port they enter. Features that enter the OutputFirst Port, will be output first, and features that enter the OutputLast Port will be output last.

This is useful for Transformers and Writers that need features to enter in a particular order. For example, Writers/FeatureWriters that rely on a separate Schema Feature to be the first to enter prior to the main data features to prevent a writing error, or Transformers that aggregates or merges groups of features and are set to only use one feature as the Attributes for the output etc.
