I think that you need to do two things and take the necessary time to
do both:
1) List on a sheet of paper all your requirements, your expectations
and what kind of tradeoffs you are ready to make for your cluster
configuration when it comes to potential data loss, and the amount of
data retention you are willing to have around. There is no way to
tell what's good or not for your product if you don't know that
first.
2) Read the documentation:
