YugaByte Database

YSQL reuses the PostgreSQL query layer, supporting most features, datatypes, and extensions, easing migration from PostgreSQL as highlighted in the core features.

Based on Google Spanner architecture, it provides ACID transactions with snapshot, serializable, and read committed isolation levels across the cluster, ensuring data correctness for mission-critical apps.

Configurable to tolerate disk, node, zone, and region failures with zero data loss (RPO=0) and rapid recovery (RTO ~3 seconds), as stated in the continuous availability section.

Scales by simply adding nodes to handle more IOPS or storage, making it suitable for growing workloads without sharding complexity.

Supports deployments across multiple zones, regions, and clouds with built-in replication and read replicas, enabling low-latency access for global applications.
