AWS Mobile Analytics Enviornment

I'm implementing AWS Mobile Analytics on an app with two environments, beta and production. It's working well with the auto export configuration S3 + Redshift but I have a doubt about the environment data split.

Should I have another Mobile Analytics with another configuration to auto export to another Redshift? Or should I have one Redshift and the two apps (beta and production) sending data to the same Redshift? In the second case I could detect from which app is the data coming by the package name that is unique.

Thanks in advance!
