Streams

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.

Stream configuration options

Field	Type	Required	Description
`name`	`string`	Yes	A descriptive name for the Stream.
`destination_id`	`uuid`	Yes	The ID of the Destination where data will be delivered.
`dataset_id`	`uuid`	Yes	The ID of the Dataset this Stream reads from.
`mappings`	`array`	Yes	An array of field mappings that transform source fields to target fields at the Destination.
`is_enabled`	`boolean`	No	Whether the Stream is actively delivering. Defaults to enabled.

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.
