A Stream connects a Dataset to a Destination and defines how records are mapped and delivered. Prequel Import orchestrates the Stream, resiliently batching, transforming, and delivering records to the configured Destination.

Mappings

Each mapping defines how a source field maps to a target field in the Destination. Mappings can either reference a Source column directly or compute a value from one or more Source columns using an expression. See Advanced Table Mapping for the two mapping categories, expression syntax, and additional supported functions.
