Scenario: Cloud migration from BigQuery to S3
User wants to backup data in bigquery into S3, to do this they start from browsing bigquery table in dataprep and create pipelines from that and attach an S3 sink
This does not work out of box because a wrangler sink gets attached even if the user has not done any transformation.
- Allow empty recipes
- If there are no directives in data prep stage do not add a wrangler transform step while going from data prep to data pipelines
