cron.py の私のコードは次のようになります。

def transactional_task():
    doStuff()
xg_on = db.create_transaction_options(xg=True)
db.run_in_transaction(xg_on, transactional_task)

ここのドキュメントから直接持ち上げた

アプリケーションエンジンが TransactionOptions を作成できないと考える理由は何ですか? 私のデータストアは高レプリケーションです。

どのドキュメント？db.run_in_transaction() は関数である最初の引数を取ります。最初の引数として TransactionOptions オブジェクトを取る run_in_transaction_options() を呼び出すつもりだったと思います。
