SurrealDB
1 min read
SurrealDB is a powerful, cloud-native, multi-model database built for modern application development. It supports relational, document, graph, vector, and real-time data access, all via a unified SQL-like query language called SurrealQL. There is also a GUI called Surrealist.
Multi-Model Support
• Relational: Traditional table structure with foreign key-like linking.
• Graph: Native support for linked data using edges and nodes.
• Vector: Built-in similarity search for AI/ML use cases.
• Real-time: Subscriptions and change feeds.
• Time-Series & Search: Native support for time-ordered and full-text queries.
SurrealQL
SurrealQL blends the familiarity of SQL with document/graph features.
sql
-- Create a user
CREATE user:john SET name = 'John Doe', email = 'john@example.com';
-- Read a record
SELECT * FROM user:john;
-- Create a relationship (graph)
RELATE user:john->friend->user:jane;
-- Search by text
SELECT * FROM article WHERE content CONTAINS 'database';
-- Vector similarity search
SELECT * FROM embeddings WHERE vector <-> [0.1, 0.2, 0.3] LIMIT 3;
