In addition to the Data Manipulation Language (DML) based APIs, Cloud Spanner supports the mutation API, where the application describes data modification using a data structure instead of a SQL statement.
This class serves as a wrapper for all mutations types. Use the builders, such as InsertMutationBuilder or UpdateMutationBuilder to create objects of this class.
