Class CommitStats (3.8.0)

CommitStats(mapping=None, *, ignore_unknown_fields=False, **kwargs)

Additional statistics about a commit. .. attribute:: mutation_count

The total number of mutations for the transaction. Knowing the mutation_count value can help you maximize the number of mutations in a transaction and minimize the number of API round trips. You can also monitor this value to prevent transactions from exceeding the system limit <http://cloud.google.com/spanner/quotas#limits_for_creating_reading_updating_and_deleting_data>. If the number of mutations exceeds the limit, the server returns INVALID_ARGUMENT <http://cloud.google.com/spanner/docs/reference/rest/v1/Code#ENUM_VALUES.INVALID_ARGUMENT>.
