What is YugabyteDB?

YugabyteDB is a high-performance, cloud-native distributed SQL database. Here are its salient points:

• Has a pluggable query layer, and supports two distributed SQL APIs:
  • Yugabyte SQL (YSQL) - PostgreSQL-compatible fully relational API
  • Yugabyte Cloud QL (YCQL) - Semi-relational SQL-like API with documents/indexing support and Apache Cassandra QL roots
• Automated sharding, Raft consensus replication and distributed transactions, based on the Google Spanner architecture
• Offers horizontal write scalability, strong write consistency and tunable read consistency (strong reads by default with follower & observer reads as options)
• Extremely resilient with native failover and repair - can tolerate disk, node, zone and region failures automatically
• Supports geo-distributed deployments (multi-zone, multi-region, multi-cloud)
• Built-in enterprise features such as distributed backups, in-flight/at-rest encryption and read replicas (for observer reads)
• Can be deployed in public clouds and natively inside Kubernetes
• Best fit for powering massively-scalable, globally-distributed, cloud-native applications that require absolute data correctness and high tolerance to failures
• 100% open source under the Apache 2.0 license
