description

string

User friendly data source description string.
clientId

string

Data source client id which should be used to receive refresh token.
scopes[]

string

Api auth scopes for which refresh token needs to be obtained. These are scopes needed by a data source to prepare data and ingest them into BigQuery, e.g., https://www.googleapis.com/auth/bigquery
transferType
(deprecated)

enum (TransferType)

Deprecated. This field has no effect.
supportsMultipleTransfers
(deprecated)

boolean

Deprecated. This field has no effect.
updateDeadlineSeconds

integer

The number of seconds to wait for an update from the data source before the Data Transfer Service marks the transfer as FAILED.
defaultSchedule

string

Indicates the type of authorization.
dataRefreshType

enum (DataRefreshType)

Specifies whether the data source supports automatic data refresh for the past few days, and how it's supported. For some data sources, data might not be complete until a few days later, so it's useful to refresh data automatically.
