FAQ

What is distributed SQL?

Distributed SQL is a single logical relational database that automatically shards and replicates data across multiple nodes, using quorum-based consensus (such as Raft) to provide strong consistency, ACID transactions, high availability, and distributed query execution. Applications see one database while the system scales horizontally and tolerates failures across zones and regions

What are the basics of SQL databases?

SQL databases store data in structured tables made up of rows and columns, and SQL (Structured Query Language) is used to create, read, update, and delete that data. Core concepts include defining schemas with data types and keys, using queries to filter and join tables, applying constraints to keep data accurate, and building indexes to keep searches fast.

Why should I leverage a distributed SQL database?

By leveraging distributed SQL, organizations can achieve elastic scalability (scaling reads and writes by adding nodes without complex sharding), high availability, and resilience. By scaling reads and writes without complex sharding, distributed SQL ensures continuous resilience through synchronous replication and self-healing. It further simplifies operation with built-in rebalancing and no primary-secondary promotions.
Global deployments across multiple regions provide low-latency access and data residency compliance, while PostgreSQL compatibility allows developers to stay productive with familiar tools.

Who benefits from a distributed SQL database?

Organizations building cloud-native, business‑critical applications are the primary beneficiaries of distributed SQL databases. These include businesses across a variety of industries seeking continuous availability, strong consistency, low latency, and global scalability. Organizations adopting a distributed SQL database report seeing consistent fault tolerance, horizontal scalability, and geo-distribution as core advantages.
