Write typed tabular rows as a Parquet artifact.
Why: Use for efficient analytical-storage artifacts.
Output: artifact; per_worker.

Platform Artifact View
On DATAMIMIC Platform, leave storageId and exportUri unset. Platform-managed artifact storage chooses the task-scoped location read by Artifact View.
Set exportUri only together with a storageId that names your own <object-storage>. It is a relative path prefix, not a filename. Outputs in custom object storage are outside Platform Artifact View.
Options: compression
targetEntity: not supported
