I agree Jeff, it really seems this way. Via the console, I don't see any difference in the indexes, however, I'm not sure what's going on under the hood. I'm hoping that someone at Google can look for me?
I imagine I can use the cost on the RPCs (a la https://gist.github.com/715284) to see if there is a difference between similar RPC calls. I would almost bet that they will be coming back double. I'll try to gather more information from my end. j On Oct 25, 12:34 pm, Jeff Schnitzer <[email protected]> wrote: > I really have to wonder if somehow you've added extra indexes during the > migration.
