What is YugaByte DB?
YugaByte DB is a high-performance, cloud-native distributed SQL database. Here are the salient points about it:
- 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, consensus replication and distributed transactions architecture based on the Google Spanner design
- Offers horizontal scalability, strong consistency, high availability
- Extremely resilient - can tolerate disk, node, zone and region failures automatically
- Supports geo-distributed deployments (multi-zone, multi-region, multi-cloud)
- Can be deployed in public clouds and natively inside Kubernetes
- Open source under the Apache 2.0 license
