I recently changed my code and added sendKey=true so that while reading I can get my actual key.
The problem is I had stored about a million keys without sendKey=true and now I have added this feature.
So what will happen on client.put() now ? i.e on update of those events which were inserted without sendKey=true
Will there be any error while updating those records ?
Also, how does sendKey=true work in case on client.put(). I am looking for explanation in terms of cached keys and stored keys.
