description CockroachDB Overview

CockroachDB is a distributed SQL database designed for resilience and scalability. Its built to handle massive workloads and provides strong consistency guarantees through its multi-region architecture. Its cloud-native design simplifies deployment and management, while its SQL interface makes it accessible to developers familiar with relational databases. It's ideal for applications requiring high availability and global data access.

help CockroachDB FAQ

What problem does CockroachDB solve compared with a single PostgreSQL server?

CockroachDB is a distributed SQL database that spreads data across multiple nodes instead of relying on one primary server. It uses a PostgreSQL-compatible SQL layer and is built for resilient, multi-region applications.

Does CockroachDB provide strong consistency?

Yes. CockroachDB is known for serializable isolation and uses consensus replication, based on Raft, to keep replicated data consistent across nodes.

Can CockroachDB survive a cloud region failure?

It can be configured for that use case. A multi-region CockroachDB cluster can place replicas across regions so the database keeps serving traffic when a node or zone fails, assuming the cluster is sized and configured correctly.

Why do developers compare CockroachDB with YugabyteDB?

Both are distributed SQL databases aimed at cloud-native applications that need horizontal scaling. CockroachDB emphasizes PostgreSQL-style SQL compatibility and transactional consistency, while YugabyteDB also targets PostgreSQL-compatible distributed workloads.
