Yugabyte DB

Uses the PostgreSQL query layer (YSQL), supporting most features, datatypes, and extensions, which eases migration from existing PostgreSQL databases and reduces learning curves.

Based on Google Spanner architecture with Raft consensus, providing strong consistency and ACID compliance across distributed nodes, essential for mission-critical OLTP applications.

Configurable to tolerate disk, node, zone, and region failures with zero data loss (RPO=0) and rapid recovery (RTO=3 seconds), ensuring continuous availability for cloud-native deployments.

Scales linearly by adding nodes to the cluster, allowing applications to handle increased IOPS and storage capacity without downtime, as highlighted in the scalability documentation.
