User Specific DB

[pete7373]

I would like each user of my application to have their own separate DB instance.  This is because each user comes from different business and so I don't want any risk of user A seeing data from user B (which could happen if query forgot to say where owningUser = 'xyz'.  Also, if all businesses share same datastore, the tables will get very big which may slow things down.

So, do I need to register multilple app instances?

I kind of want one app instance, but multilpe data stores, is this possible?

hi,

You can use namespaces to support multitenancy -- see this page for more information: http://code.google.com/appengine/docs/python/multitenancy/overview.html

FYI, this is not an issue with the GAE datastore. Your data already
lives in a very, very large table along with terabytes (petabytes?) of
other people's data. A "BigTable".
