Reference documentation and code samples for the Google Cloud Datastore v1 API class TransactionOptions.
Options for beginning a new transaction.
Transactions can be created explicitly with calls to
[Datastore.BeginTransaction][google.datastore.v1.Datastore.BeginTransaction]
or implicitly by setting
[ReadOptions.new_transaction][google.datastore.v1.ReadOptions.new_transaction]
in read requests.
