Provide strong consistency in Redis Cluster

I need to load static data one time in redis in the master node and only when the synchronization is finished for all slaves I am going to be able to read. This is because we are going to have a lot reading and a few writing, and the data is not going to change for a long time.

I read from oficial documentation Redis cluster tutorial – Redis in Redis Cluster consistency guarantees.

I read also Can the WAIT command provide strong consistency in Redis? but without to get a conclusion.

If I use synchronous replication and wait command to check if the replication was successful, do I have some guarantees about consistency ?

What is the best trusted way to get consistency ? I am not worried abut availability, because I need performance and consistency.

Thank you.
