⚡️Lightning fast in-memory VectorDB written in rust🦀

MemVectorDB

An fast in-memory VectorDB in rust.

⚡️ Features

• Fast: MemVectorDB stores vectors in-memory, ensuring fast insertion and retrieval operations.
• Vertical Scalability: With vectors stored in-memory, MemVectorDB can scale vertically based on available system resources.
• Metadata Support: Supports metadata storage, beneficial for RAG (Retrieval Augmented Generation) applications and pipelines.
• Open Source: MIT Licensed, free forever.

memvectordb's Issues

Enhancement: Add logging

• Implement logging of changes made to db instance.

Enhancement: Option for persistence

Functionality to the system to allow for data persistence, meaning the ability to store data beyond the runtime of the application for user's that require that.

Enhancement: Implement Semantic Search Functionality

This feature is to enhance the functionality of the vector database by introducing semantic search capabilities.
Semantic search enables users to retrieve results that are contextually relevant to their query, beyond just keyword matching.

Optimize `CacheDB`.`insert_into_collection` method to O(1) Time Complexity

• replace the linear scan for duplicate IDs with a constant-time operation using HashMap for fast ID lookup.
• Might have to modify the Collection and Embedding structs.
• Goal is to provide O(1) average-time complexity for checking if an embedding ID already exists.
