format or, for custom format jobs, its mapping. See Message formats for built-in format options.
You configure destinations to control how extracted data is stored, organized, and governed within CDF.
What destinations are
A destination contains a CDF session (credentials) and an optionaltargetDataSetId that scopes all data written through it to a specific data set. Multiple jobs can share one destination; when they do, their requests are combined, reducing the number of calls made to CDF APIs while metrics are still reported per job.
Creating and managing destinations
You create a destination by providing anexternalId and CDF credentials. Once created, you reference the destination by its externalId when creating a job. You can update the credentials or data set ID, and delete a destination when it is no longer associated with any jobs.
Grant destination credentials access only to the CDF resources the extractor needs to write. See Hosted extractors overview for the required capabilities per output type.
