When mode is TRANSACTIONAL, mutations affecting a single entity are
applied in order. The following sequences of mutations affecting a single
entity are not permitted in a single Commit request:
insert followed by insert
update followed by insert
upsert followed by insert
delete followed by update
When mode is NON_TRANSACTIONAL, no two mutations may affect a single
entity.
public TransactionOptions SingleUseTransaction { get; set; }
Options for beginning a new transaction for this request.
The transaction is committed when the request completes. If specified,
[TransactionOptions.mode][google.datastore.v1.TransactionOptions] must be
[TransactionOptions.ReadWrite][google.datastore.v1.TransactionOptions.ReadWrite].
The identifier of the transaction associated with the commit. A
transaction identifier is returned by a call to
[Datastore.BeginTransaction][google.datastore.v1.Datastore.BeginTransaction].
