Based on ticket https://redislabs.atlassian.net/browse/MOD-8384
The above document line in the example should change to add "prefix=", as below:
Change from:
gb.register('person:*') # Only process keys matching the pattern 'person:*'
To be:
gb.register(prefix='person:*') # Only process keys matching the pattern 'person:*'
I'll mention this on the docs slack channel.
