Hi n8gray, There's currently no support for an 'exists' operation. A key only query as bd_ describes would work, but I would expect the execution time for such a query to be at least as long as a simple get(). Unless your entity is exceptionally large, a straightforward get() is likely to be only marginally slower than an 'exists' operation would be.
