CockroachDB: SQL for Global Scale Design Principles

CockroachDB is a distributed SQL database designed for global scalability and resilience. The database achieves this through a unique architecture built on a monolithic key-value store, Raft-based replication, and hybrid logical clocks. Transaction management is optimized for global workloads using a non-blocking commit protocol and multi-region capabilities. CockroachDB offers declarative data locality, enabling administrators to define data placement policies for performance and compliance. Performance optimization strategies, like follower reads and elastic scaling, help reduce latency…
