LlamaIndex Chat_Store Integration: DynamoDB Chat Store

This enables AWS DynamoDB to be used as a chat store.

Installation

pip install llama-index-storage-chat-store-dynamodb

Usage

Assumptions

• SessionID, a string, is used as the partition key.

• The table used for the chat store already exists. Here is an example for that:

  import boto3
  
  dynamodb = boto3.resource("dynamodb")
  
  # Create the DynamoDB table.
  table = dynamodb.create_table(
      TableName="EXAMPLE_TABLE",
      KeySchema=[{"AttributeName": "SessionId", "KeyType": "HASH"}],
      AttributeDefinitions=[
          {"AttributeName": "SessionId", "AttributeType": "S"}
      ],
      BillingMode="PAY_PER_REQUEST",
  )
  

Using an AWS IAM Role

You can use any of the following AWS arguments to setup the required boto3 resource connection:

• profile_name
• aws_access_key_id
• aws_secret_access_key
• aws_session_token
• botocore_session - A pre-existing existing Botocore session.
• botocore_config

As an example, if you have already assumed an AWS profile in your local environment or within an AWS compute environment, you can simply do the following:

import os
from llama_index.storage.chat_store.dynamodb.base import DynamoDBChatStore

store = DynamoDBChatStore(
    profile_name=os.getenv("AWS_PROFILE"),
    table_name="EXAMPLE_TABLE",
    session_id="123",
)
