Distributed SQL databases like YugabyteDB offer high availability, horizontal scalability, and geo-distribution of data, making them ideal for organizations operating across multiple regions. Unlike single-node systems like traditional PostgreSQL, distributed SQL operates on a cluster of nodes, providing benefits such as automatic healing and re-replication during infrastructure failures, effortless horizontal scaling, and flexible geo-deployment options. However, this comes with behavioral differences, including higher network latencies due to the need to traverse multiple nodes, potential transaction conflicts, and the requirement for connection pooling to minimize latency penalties. YugabyteDB is actively enhancing its performance by improving expression pushdowns functionality, packed rows, and batched nested loops, as well as optimizing connection management through built-in connection pooling and local cache loading. While PostgreSQL remains a great option for traditional single-node database requirements, YugabyteDB presents an increasingly compelling choice for applications that need scalability, resilience, and geo-distributed/data residency capabilities provided by its distributed architecture.
