title: Wipe clean all data from GAE datastore
body: <p>I have about 20GB of data in the datastore.
  The builtin indexes (which I have no control over) have increased to ~200GB.</p>
  
  <p>I backed up all the data to BigQuery and don't need it anymore.</p>
  
  <p>I am trying to get out of the datastore, but I can't - datastore Admin console can't delete that many entities (bulk delete option uses map reduce, which fails on quota within an hour or so), and the cost of deleting each entity programatically is too expensive (> $1000 - many write operations because of the many indexes).
  Meanwhile google charges me $50/month for storing the data I don't need :(</p>
  
  <p>how do I: Close my datastore project (not the app engine project, just the datastore part of it), or just wipe out all the data?</p>
  
  <p>Please help me get out of this!</p>
