Weaviate
Weaviate is an open-source vector database that stores both objects and vectors, allowing for the combination of vector search with structured filtering with the fault tolerance and scalability of a cloud-native database.
Today, i'll like to share a technique that i recently discovered whilst trying to measure how long it takes to execute a method or function in .NET. I faced this challenge when working with the vector search component of Weaviate. Weaviate is open-source vector database state-of-the-art machine learning (ML) models to turn your data - text, images, and more - into a searchable vector database. It stores both objects and vectors, allowing for the combination of vector search with structured filtering. Thus, the performance of search is integral especially for a database.
