The article compares PostgreSQL and CockroachDB, two popular databases. It highlights that while PostgreSQL is reliable and widely used, it has limitations in terms of scale, resilience, and geographic expansion. On the other hand, CockroachDB offers native horizontal scaling without operational overhead, built-in high availability, and the ability to deliver a single logical database across multiple regions. Importantly, CockroachDB is compatible with PostgreSQL, allowing users to leverage their existing tools and services. The author encourages readers to try out CockroachDB for free at cockroachlabs.cloud.
