Cheapest way to import over 10m entities to app engine

Question

Is there a cheap way to import bulk data into app engine without paying for the datastore write operations?

I estimate that loading my 10m+ entities would cost 100+ dollars to get my data into app engine is there any other way? It seems like (accounting for indexs) each entity is taking 10 write operations can I cut it down to 1 write operation somehow?

Thanks

App Engine maintains built-in indexes for each indexed property (i.e. those that don't have indexed=False as a parameter when defining the property). See http://code.google.com/appengine/articles/index_building.html for more details.

If there are properties that won't appear in any of your queries, specify indexed=False as you are defining the property. This will save you the cost of the index write operations associated with such properties that you don't need to be automatically indexed.
