public sealed class BigQuerySource : IMessage<BigQuerySource>, IEquatable<BigQuerySource>, IDeepCloneable<BigQuerySource>, IBufferMessage, IMessage
The BigQuery location for input data. If used in an [EvaluationJob][google.cloud.datalabeling.v1beta1.EvaluationJob], this
is where the service saves the prediction input and output sampled from the
model version.
Required. BigQuery URI to a table, up to 2,000 characters long. If you
specify the URI of a table that does not exist, Data Labeling Service
creates a table at the URI with the correct schema when you create your
[EvaluationJob][google.cloud.datalabeling.v1beta1.EvaluationJob]. If you specify the URI of a table that already exists,
it must have the
correct
schema.
