Hi there,
I've started to look at using the new CloudTrace API to add information on 
CloudSQL requests to traces on AppEngine requests, which we desperately 
need, but I encountered two challenges:

First, even batching all the traces for a request together in a single API 
call adds about 100 ms latency to the request (that's the /urlfetch.Fetch 
bar below), which I don't think I can stomach in production. Is there 
anyway to piggy back custom trace data onto AppEngine's existing reporting 
mechanism, which seems to run independently of requests? 

Second, is there any way to detect which requests AppEngine has sampled for 
tracing so that we only spend the time to report traces for those that are 
sampled for RPC traces?

Thanks,
Alex
