PlanetScale has announced the general availability of vector support, a significant enhancement for MySQL users. As a fork of MySQL, PlanetScale now enables storing vector data alongside relational data, eliminating the need for a separate vector database. This integration simplifies AI and machine learning workflows by keeping vector embeddings directly within your existing MySQL infrastructure.

You Should Know:
1. Setting Up PlanetScale with Vector Support
To enable vector support in PlanetScale, follow these steps:
- Create a PlanetScale Database (if you don’t have one):
pscale database create <database-name> --region <region>
2. Enable Vector Extension:
ALTER DATABASE your_database_name ENABLE VECTOR;
3. Create a Table with Vector Columns:
CREATE TABLE products ( id INT AUTO_INCREMENT PRIMARY KEY, name VARCHAR(255), description TEXT, embedding VECTOR(1536) -- OpenAI embeddings typically use 1536 dimensions );
2. Inserting and Querying Vectors
- Insert a Vector:
INSERT INTO products (name, description, embedding) VALUES ('Laptop', 'High-performance laptop', '[0.1, 0.5, ..., 0.2]'); - Search Similar Vectors (Cosine Similarity):
SELECT name, description FROM products ORDER BY COSINE_DISTANCE(embedding, '[0.3, 0.1, ..., 0.4]') LIMIT 5;
3. Integrating with AI Models
Use Python to generate embeddings and store them in PlanetScale:
import openai
import pymysql
Generate embedding using OpenAI
response = openai.Embedding.create(input="Your text here", model="text-embedding-ada-002")
embedding = response['data'][bash]['embedding']
Store in PlanetScale
conn = pymysql.connect(host='your-host', user='user', password='pass', database='db')
cursor = conn.cursor()
cursor.execute("INSERT INTO products (embedding) VALUES (%s)", (str(embedding),))
conn.commit()
4. Performance Optimization
- Indexing Vectors:
CREATE INDEX idx_embedding ON products USING IVFFLAT (embedding) WITH (lists = 100);
- Benchmarking Queries:
EXPLAIN ANALYZE SELECT FROM products ORDER BY COSINE_DISTANCE(embedding, '[0.1,...]') LIMIT 10;
What Undercode Say:
PlanetScale’s vector support bridges the gap between relational databases and AI-driven applications. By consolidating vector data within MySQL, developers reduce architectural complexity. Key takeaways:
– No More Separate Vector DBs: Avoid managing additional infrastructure.
– SQL-Powered AI: Leverage familiar query syntax for semantic search.
– Scalability: PlanetScale’s distributed backend ensures low-latency vector searches.
For DevOps teams, this means easier MLOps pipelines. For app developers, faster AI integrations. The future of MySQL is vector-ready.
Expected Output:
A scalable, AI-enhanced database solution with native vector search capabilities.
