Introduction to Weaviate

In today’s technology landscape, data is at the heart of every intelligent application. Weaviate is an open-source, scalable, and highly efficient vector search engine that allows developers to build powerful data-driven applications.

What is Weaviate?

Weaviate not only supports traditional data models but also integrates advanced machine learning capabilities. It’s built around the concept of GraphQL, which provides a seamless way to query and retrieve data. 

Key Features of Weaviate

  • GraphQL Interface: Simplifies data queries.
  • Deep Learning Integration: Easily implement ML models.
  • Real-time Updates: Data consistency is maintained instantly.
  • Highly Scalable: Suitable for large datasets and demands.

How to Install Weaviate

To get started with Weaviate, you need to follow these steps:

Requirements

  • Docker: Ensure you have Docker installed on your machine.
  • Docker Compose: Required to orchestrate multi-container Docker applications.
