  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

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 For quick setup in docker environment: 
    docker pull jaguardb/jaguardb
docker run -d -p 8888:8888 -p 8080:8080 --name jaguardb  jaguardb/jaguardb
    Without Docker, run: 
    curl -fsSL http://jaguardb.com/install.sh | sh
    This installs both the Jaguar vector database and HTTP gateway. The servers will start automatically after installation.
  2. You must install the http client package for JaguarDB: 
        pip install -U jaguardb-http-client
  3. You’ll need to install langchain-community with pip install -qU langchain-community to use this integration
