The CAP Theorem and Its Implications for Postgres, MongoDB, Kafka, Cassandra
The CAP theorem is a fundamental principle in the realm of distributed systems, stating that a distributed database system can guarantee only two out of the following three properties at the same time: Consistency (C), Availability (A), and Partition Tolerance (P). This theorem has profound implications for the architecture and selection of database systems in software development. This article focuses on Postgres, MongoDB, Kafka, and Cassandra, and how each of these systems addresses the challenges posed by the CAP theorem.
