### Method Details

`insertAll(projectId, datasetId, tableId, body=None)`

    Streams data into BigQuery one record at a time without needing to run a load job. Requires the WRITER dataset role.

    Args:
      projectId: string, Project ID of the destination table. (required)
      datasetId: string, Dataset ID of the destination table. (required)
      tableId: string, Table ID of the destination table. (required)
      body: object, The request body.
        The object takes the form of:

    {
        "rows": [ # The rows to insert.
          {
            "insertId": "A String", # [Optional] A unique ID for each row. BigQuery uses this property to detect duplicate insertion requests on a best-effort basis.
            "json": { # Represents a single JSON object. # [Required] A JSON object that contains a row of data. The object's properties and values must match the destination table's schema.
              "a_key": "",
            },
          },
        ],
        "kind": "bigquery#tableDataInsertAllRequest", # The resource type of the response.
        "templateSuffix": "A String", # If specified, treats the destination table as a base template, and inserts the rows into an instance table named "{destination}{templateSuffix}". BigQuery will manage creation of the instance table, using the schema of the base template table. See https://cloud.google.com/bigquery/streaming-data-into-bigquery#template-tables for considerations when working with templates tables.
        "ignoreUnknownValues": True or False, # [Optional] Accept rows that contain values that do not match the schema. The unknown values are ignored. Default is false, which treats unknown values as errors.
        "skipInvalidRows": True or False, # [Optional] Insert all valid rows of a request, even if invalid rows exist. The default value is false, which causes the entire request to fail if any invalid rows exist.
      }

    Returns:
      An object of the form:

        {
        "insertErrors": [ # An array of errors for rows that were not inserted.
          {
            "errors": [ # Error information for the row indicated by the index property.
              {
                "message": "A String", # A human-readable description of the error.
                "location": "A String", # Specifies where the error occurred, if present.
                "debugInfo": "A String", # Debugging information. This property is internal to Google and should not be used.
                "reason": "A String", # A short error code that summarizes the error.
              },
            ],
            "index": 42, # The index of the row that error applies to.
          },
        ],
        "kind": "bigquery#tableDataInsertAllResponse", # The resource type of the response.
      }

`list(projectId, datasetId, tableId, pageToken=None, maxResults=None, selectedFields=None, startIndex=None)`

    Retrieves table data from a specified set of rows. Requires the READER dataset role.

    Args:
      projectId: string, Project ID of the table to read (required)
      datasetId: string, Dataset ID of the table to read (required)
      tableId: string, Table ID of the table to read (required)
      pageToken: string, Page token, returned by a previous call, identifying the result set
      maxResults: integer, Maximum number of results to return
      selectedFields: string, List of fields to return (comma-separated). If unspecified, all fields are returned
      startIndex: string, Zero-based index of the starting row to read

    Returns:
      An object of the form:

        {
        "totalRows": "A String", # The total number of rows in the complete table.
        "etag": "A String", # A hash of this page of results.
        "rows": [ # Rows of results.
          {
            "f": [ # Represents a single row in the result set, consisting of one or more fields.
              {
                "v": "",
              },
            ],
          },
        ],
        "pageToken": "A String", # A token used for paging results. Providing this token instead of the startIndex parameter can help you retrieve stable results when an underlying table is changing.
        "kind": "bigquery#tableDataList", # The resource type of the response.
      }

`list_next(previous_request, previous_response)`

    Retrieves the next page of results.

    Args:

      previous_response: The response from the request for the previous page. (required)
