@Nicole-Ann_Menezes Here are some pictures of what @Christian_Dahlqvist was describing...in short in each cluster you write to the Leader and read from both the Leader and Follower... These are just high level obviously there are many details but hope this helps a bit.
Here are a couple architecture diagrams to think about... The first is more what you two are describing...
And a Failed Cluster Scenario
And a different more local architecture as well...
Then from there you can work on your failure scenarios ... like the one you mentioned...
