Metadata about a ResultSet or PartialResultSet.

Attributes

• rowType (StructType): Indicates the field names and types for the rows in the result set. For example, a SQL query like `"SELECT UserId, UserName FROM Users"` could return a `row_type` value like: "fields": [ { "name": "UserId", "type": { "code": "INT64" } }, { "name": "UserName", "type": { "code": "STRING" } }, ] Defaults to: null.
• transaction (Transaction): If the read or SQL query began a transaction as a side-effect, the information about the new transaction is yielded here. Defaults to: null.
