BigqueryJobExtract class final

extract job-type block. Exports either a table (sourceTable) or an ML model (sourceModel) to one or more Cloud Storage destinations (destinationUris, required). Provide exactly one of sourceTable / sourceModel.

Tables with nested or repeated fields cannot be exported as CSV. For Avro outputs, useAvroLogicalTypes controls how TIMESTAMP / DATETIME / etc. surface in the Avro schema.
