Thanks for the reply, Jordan.

I also saw there is a separate group for discussions about Google Cloud 
Datastore.
( https://groups.google.com/forum/#!forum/gcd-discuss )
I probably should have posted there first / instead of in this group.

We do have existing Java code in our server (deployed to a Google App 
Engine environment)
which accesses our datastores via Java libraries.

We do use the Cloud Console, mostly in a limited and ad hoc manner, as 
needed
for some tasks as part of DevOps, debugging, testing, etc..

I was just curious about a possible existing command-line tool which might
(a) have advantages over the Cloud Console, (b) be used as a sanity 
check for comparison
with the results we are seeing from our Java code. 

Thanks again for your input,

Brian
