title: What is the most efficient way to write 3GB of data to datastore?
body: <p>I have a 3Gb csv file. I would like to write all of the data to GAE datastore. I have tried reading the file row by row and then posting the data to my app, but I can only create around 1000 new entities before I exceed the free tier and start to incur pretty hefty costs. What is the most efficient / cost effective way to upload this data to datastore?</p>
