a couple of thoughts... 1. i don't know for sure about datastore connecting to GCE, but the beta managed VMs project allows you to run a GCE instance with full connection to the app engine datastore (and other services). We have used it well in python for types of processing that we couldn't run on regular app engine instances. 2. i don't know if there are limit on datastore entity kinds per project. 3. i like your approach 1 as it seems much easier to code and use to me.
just my 3 cents... cfh On Sunday, January 31, 2016 at 5:14:28 AM UTC-8, Dhanunjaya Naidu. Yandrapu wrote: > > Hi, > > I am new to Google cloud and have few question. I have few questions.
