Class TableListItem (3.21.0)

TableListItem(resource)

A read-only table resource from a list operation.

For performance reasons, the BigQuery API only includes some of the table properties when listing tables. Notably, xref_schema and xref_num_rows are missing.

For a full list of the properties that the BigQuery API returns, see the REST documentation for tables.list <https://cloud.google.com/bigquery/docs/reference/rest/v2/tables/list>_.

`resource`	`Dict[str, object]` A table-like resource object from a table list response. A `tableReference` property is required.

Union[int, None]: Expiration time in milliseconds for a partition.

If this property is set and type_ is not set, type_ will default to TimePartitioningType.DAY.
