Since its inception in 2011, Google App Engine High Replication Datastore (HRD) has grown and currently processes over 4.5 trillion transactions per month with 99.95% uptime. In addition, HRD serves as the basis of Google Cloud Datastore, which we announced last week at Google I/O.

We are always evaluating opportunities to create more value for you and today we are reducing Datastore prices by up to 25%. This price change impacts both App Engine HRD and Cloud Datastore.
