But we can only pick two out of three at a time and that totally depends on our prioritize based on requirements.
What is Data Consistency?
Consistency means that any read request will return the most recent write.

What is Availability?
Availability means that a non-responding node must respond in a reasonable amount of time. Not every application needs to run 24/7 with 99.999% availability but most likely you will prefer a database with higher availability.
