Fields
`projectId`	`string` The project ID (can be project # or ID) that the BigQuery source is in with a length limit of 128 characters. If not specified, inherits the project ID from the parent request.
`datasetId`	`string` Required. The BigQuery data set to copy the data from with a length limit of 1,024 characters.
`tableId`	`string` Required. The BigQuery table to copy the data from with a length limit of 1,024 characters.
`gcsStagingDir`	`string` Intermediate Cloud Storage directory used for the import with a length limit of 2,000 characters. Can be specified if one wants to have the BigQuery export to a specific Cloud Storage directory.
`dataSchema`	`string` The schema to use when parsing the data from the source. Supported values for user event imports: `user_event` (default): One `UserEvent` per row. Supported values for document imports: `document` (default): One `Document` format per row. Each document must have a valid `Document.id` and one of `Document.json_data` or `Document.struct_data`. `custom`: One custom data per row in arbitrary format that conforms to the defined `Schema` of the data store. This can only be used by the GENERIC Data Store vertical.
Union field `partition`. BigQuery table partition info. Leave this empty if the BigQuery table is not partitioned. `partition` can be only one of the following:
`partitionDate`	`object (Date)` BigQuery time partitioned table's _PARTITIONDATE in YYYY-MM-DD format.
