[google-appengine] Re: Is there a possible way to have two datastores for the same application?

2016-04-11 Thread Anastasios Hatzis 
Youssef, if I remember correctly, you can only have one datastore and one 
app-engine in a Google cloud project. However, you should be able to access 
entities of a different datastore (i.e. in a different project) by defining 
the app parameter in the NDB Key constructor 
. 
Certainly, you would need to manually add permissions for your app in the 
other (test) datastore.

Alternatively, you could use just the same datastore, but a different 
namespace, e.g. "test". Or if you already use namespaces for multi-tenancy, 
you could have multiple namespaces test-1, test-2 etc. to run tests 
regarding multi-tenancy features.

While you could use namespaces 
 to 
achieve this, you need to consider what it means to have two 'environments' 
running together, and what are the consequences of mistakes.

Generally we've found the simplest option is to have extra cloud projects 
for extra environments, which is usually very cheap/free assuming you 
aren't simulating real loads constantly. Obviously there are some drawbacks 
to this, such as ease of code promotion, but if you're using other services 
in google cloud, they aren't intrinsically namespace aware, so you need to 
be careful.

We use separate projects as well and it works reasonably well. It makes it much 
less stressful to push builds to the test environment. 

Unfortunately you are likely to need some sort of mechanism to change 
configuration between environments. For example, if you use google cloud 
storage, bucket names must be globally unique so you have to store or derive 
the root bucket names for each environment.
