Explore innovative database indexing and distributed architecture capabilities
The number of indices available in Postgres is remarkable. Additionally, the way it forks each process into a child node, instead of executing in the same node, is quite different from most databases. These features can be especially useful in certain scenarios compared to MySQL or other SQL-based databases. Also, the ability to distribute the database across different machines is a significant advantage.

Helps convert text and other data into a vector space but could provide detailed insights
Milvus is an open-source vector database designed for efficiently handling large-scale, high-dimensional data. It supports various types of data sources and can be deployed on your own premises, which is crucial for maintaining data security. Milvus offers multiple methods for calculating similarities or distances between vectors, such as L2 norm and cosine similarity. These methods help in comparing different vectors based on specific use cases. For instance, in our use case, we find that the L2 distance works best, but you can experiment with different methods to find the most suitable one for your needs. Milvus also includes its own user interface, known as the Milvus Dashboard, which allows you to visualize and manage your data, including embeddings and metadata. You can filter your data based on various criteria, including metadata and file names, which provides flexibility in data management.
