Writes require a quorum of distributed nodes to commit, ensuring strict serializability without split-brain anomalies.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Q2: Is distributed SQL faster than a traditional single-node database?<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For simple single-region write operations, a local monolithic database often has lower baseline latency because it avoids cross-network consensus handshakes. However, for massive write volumes, large data footprints, and global multi-region deployments, distributed SQL provides far higher total throughput, automated horizontal scaling, and eliminates single-node resource saturation.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Q3: How does geo-partitioning work in distributed SQL engines?<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Geo-partitioning allows administrators to define database rules that map specific rows, partitions, or tables to storage nodes located within designated geographical borders. This keeps read\/write latency low for local users and directly solves regulatory data residency mandates.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Legacy relational databases (like single-node PostgreSQL or MySQL) were engineered under an assumption that hardware would scale vertically inside a single data center.
