I'm new to Google cloud Spanner, please help What is Mutation class. How mutation works? Please give me explanation because below link dosen't explained it properly [https://developers.google.com/resources/api-libraries/documentation/spanner/v1/java/latest/com/google/api/services/spanner/v1/model/Mutation.html]
As specified in the documentation:
A mutation represents a sequence of inserts, updates, and deletes that Cloud Spanner applies atomically to different rows and tables in a Cloud Spanner database.
You can also see in this link how to insert, update, and delete data using mutations, in order to know how it works.
