Attributes

Name Description
table :noindex: str
Optional. The name of the table to which to write data, of the form {projectId}.{datasetId}.{tableId}
use_topic_schema :noindex: bool
Optional. When true, use the topic's schema as the columns to write to in BigQuery, if it exists. use_topic_schema and use_table_schema cannot be enabled at the same time.
write_metadata :noindex: bool
Optional. When true, write the subscription name, message_id, publish_time, attributes, and ordering_key to additional columns in the table. The subscription name, message_id, and publish_time fields are put in their own columns while all other message properties (other than data) are written to a JSON object in the attributes column.
drop_unknown_fields :noindex: bool
Optional. When true and use_topic_schema is true, any fields that are a part of the topic schema that are not part of the BigQuery table schema are dropped when writing to BigQuery. Otherwise, the schemas must be kept in sync and any messages with extra fields are not written and remain in the subscription's backlog.
state :noindex: google.pubsub_v1.types.BigQueryConfig.State
Output only. An output-only field that indicates whether or not the subscription can receive messages.
use_table_schema :noindex: bool
Optional. When true, use the BigQuery table's schema as the columns to write to in BigQuery. use_table_schema and use_topic_schema cannot be enabled at the same time.
