"Consistency, Availability, Partition tolerance — pick two" is both a proven theorem and a huge oversimplification. Categorizing systems as CP, CA and AP is no longer enough in the light of configurable consistency and cloud services advertising themselves as "almost CAP". What's left of this famous theorem in 2021?
Let's deep dive into the CAP theorem in a non-academic way to identify its practical implications. During the session, we will go through some modern data stores like Cassandra, Kafka & AWS S3 to identify their place in the grey area of the CAP triangle. The audience will get an overview of possible trade-offs and their consequences for not only the three original properties.
