Task Queue Java API Overview - Google App Engine - Google Code
Today I implemented the Task Queue functionality on Quote Crate in an effort to speed up saving quotes. Basically instead of adding things to the index on save it fires off what is essentially a background task to add the quote to the index. Since it’s not getting much traffic (or any really) things are added almost immediately and the request to save quotes is sped up a bit.
Next up, exposing search.
