## Jaguar Vector Database

1.  It is a distributed vector database
2.  The “ZeroMove” feature of JaguarDB enables instant horizontal scalability
3.  Multimodal: embeddings, text, images, videos, PDFs, audio, time series, and geospatial
4.  All-masters: allows both parallel reads and writes
5.  Anomaly detection capabilities
6.  RAG support: combines LLM with proprietary and real-time data
7.  Shared metadata: sharing of metadata across multiple vector indexes
8.  Distance metrics: Euclidean, Cosine, InnerProduct, Manhatten, Chebyshev, Hamming, Jeccard, Minkowski

## Prerequisites[​](#prerequisites "Direct link to Prerequisites")

There are two requirements for running the examples in this file. 1. You must install and set up the JaguarDB server and its HTTP gateway server. Please refer to the instructions in: [www.jaguardb.com](http://www.jaguardb.com/) For quick setup in docker environment: docker pull jaguardb/jaguardb\_with\_http docker run -d -p 8888:8888 -p 8080:8080 –name jaguardb\_with\_http jaguardb/jaguardb\_with\_http

1.  You must install the http client package for JaguarDB:
    
    ```
        pip install -U jaguardb-http-client
    ```
    

## RAG With Langchain[​](#rag-with-langchain "Direct link to RAG With Langchain")

This section demonstrates chatting with LLM together with Jaguar in the langchain software stack.

## Interaction With Jaguar Vector Store[​](#interaction-with-jaguar-vector-store "Direct link to Interaction With Jaguar Vector Store")

Users can interact directly with the Jaguar vector store for similarity search and anomaly detection.
