YDB is an open-source distributed SQL DBMS written in C++ that combines horizontal scalability, high availability, and strict consistency with ACID transactions across nodes. It supports row-oriented and column-oriented tables, persistent topics (Kafka-compatible), vector search, federated queries, and a PostgreSQL-compatible mode, deployable via Ansible, Kubernetes, or manually.
Use cases
- run a horizontally scalable SQL database with ACID transactions across multiple nodes
- build a fault-tolerant OLTP service that survives datacenter outages
- run transactional and analytical (HTAP) workloads on row and columnar tables
- store and query vector embeddings for semantic search or RAG pipelines
- stream table changes to downstream systems via change data capture
- query external data sources with federated SQL queries
- connect from LLM agents to the database via MCP
When to choose
- you need strict consistency and distributed ACID transactions at scale
- you want one database for OLTP, OLAP, and streaming workloads
- you need multi-datacenter fault tolerance with automatic disaster recovery
- you want vector search integrated into a transactional SQL database
- you need PostgreSQL or Kafka wire compatibility for easier migration
When to avoid
- you need a simple single-node embedded database for a small app
- your team cannot operate a complex distributed cluster
- you depend on a rich ecosystem of third-party tools built for mainstream databases
- you need mature support on non-x86_64 platforms
