We have a multi-tenant saas. Namespaces are used to separate the data between tenants

Is there a way to query for data across namespaces.

Why do I need it? I need for internal reporting and analysis and migration purposes.

1. The answer seems to be 'No' i.e. no direct way. See - https://stackoverflow.com/a/27085337

2. You'll probably have to loop through all of your namespaces. To get all the namespaces in your datastore, see - https://googleapis.dev/ruby/google-cloud-datastore/latest/index.html which says

.....The special entity kind __namespace__ can be used to find all the namespaces used in your application entities....
