In the previous article, we saw different modules in IRIS AI Studio and how it could help explore GenAI capabilities out of IRIS DB seamlessly, even for a non-technical stakeholder. In this article, we will deep dive into "Connectors" module, the one that enables users to seamlessly load data from local or cloud sources (AWS S3, Airtable, Azure Blob) into IRIS DB as vector embeddings, by also configuring embedding settings like model and dimensions.

Connectors

If you have used ChatGPT 4 or other LLM services where they get the context and run the intelligence on top of that context, that ideally adds business value over a generic LLM. Simply the intelligence on your data. This module out of box gives a no-code interface to load data from different sources, do embeddings on it and load it to IRIS DB. This connectors module mainly go through 3 steps

1. Fetching data from different sources
2. Getting the data embedded using OpenAI/Cohere embedding models
3. Loading the embeddings and text into IRIS DB

Step 1: Fetching data from different source

1. Local Storage - Upload files. I have used Llama Index's SimpleDirectoryReader to load data from files. 

(a limitation of up to 10 files in one go is put to handle the load on tiny server that I used for demo purpose. Can be negated on your own implementation)

# Check for uploaded files
if "files" not in request.files:
  return jsonify({"error": "No files uploaded"}), 400
uploaded_files = request.files.getlist("files")
if len(uploaded_files) > 10:
  return jsonify({"error": "Exceeded maximum file limit (10)"}), 400
temp_paths = []
for uploaded_file in uploaded_files:
  fd, temp_path = tempfile.mkstemp()
  with os.fdopen(fd, "wb") as temp:
    uploaded_file.save(temp)
  temp_paths.append(temp_path)

# Load data from files
documents = SimpleDirectoryReader(input_files=temp_paths).load_data()

 2. AWS S3

Input Parameters: Client ID, Client Secret and Bucket Name. You may get the client id and secret from the AWS console - IAM or creating read permissions for your bucket over there.

I have used "s3fs" library to fetch the contents from AWS S3 and Llama Index's SimpleDirectoryReader to load data from the fetched files.

access_key = request.form.get('aws_access_key')
secret = request.form.get('aws_secret')
bucket_name = request.form.get('aws_bucket_name')

if not all([access_key, secret, bucket_name]):
    return jsonify({"error": "Missing required AWS S3 parameters"}), 400
s3_fs = S3FileSystem(key=access_key, secret=secret)
reader = SimpleDirectoryReader(input_dir=bucket_name, fs=s3_fs, recursive=True)
documents = reader.load_data()

3. Airtable

Input Parameters: Token (API Key), Base ID and Table ID. API Key can be retrieved from the Airtable's Developer Hub. Base ID and Table ID can be found from the table's URL. The one that starts with "app.." is the base ID and "tbl.." is the Table ID

I have used Airtable Reader from LlamaHub to fetch the contents from Airtable and Llama Index's SimpleDirectoryReader to load data from the fetched files.

airtable_token = request.form.get('airtable_token')
table_id = request.form.get('table_id')
base_id = request.form.get('base_id')

if not all([airtable_token, table_id, base_id]):
        return jsonify({"error": "Missing required Airtable parameters"}), 400
reader = AirtableReader(airtable_token)
documents = reader.load_data(table_id=table_id, base_id=base_id)

4. Azure Blob Storage: 

Input Parameters: Container name and Connection string. These information can be retrieved from Azure's AD page. 

I have used AzStorageBlob Reader from LlamaHub to fetch the contents from Azure Storage and Llama Index's SimpleDirectoryReader to load data from the fetched files.

container_name = request.form.get('container_name')
connection_string = request.form.get('connection_string')

if not all([container_name, connection_string]):
    return jsonify({"error": "Missing required Azure Blob Storage parameters"}), 400
loader = AzStorageBlobReader(
    container_name=container_name,
    connection_string=connection_string,
)
documents = loader.load_data()

LlamaHub does contain 500+ connectors ranging from different file types to services. Adding a new connector based on your needs should be pretty straight forward. 

Step 2: Getting the data embedded using OpenAI/Cohere embedding models

Embeddings are numerical representations that capture the semantics of text, enabling applications like search and similarity matching. Ideally the objective is, when an user asks a question, its embedding is compared to document embeddings using methods like cosine similarity – higher similarity indicates more relevant content. 

Here, I'm using llama-iris library to store embeddings into IRIS DB. In the IRISVectorStore params

• Connection String is needed for interaction with DB
  • For trying out in the online demo version, you may not use a locally running instance (localhost).
  • You would need an IRIS instance that runs on AWS/Azure/GCP with 2024.1+ version, since those support vector storage and retrieval.
  • The IRIS Community instance provided by the learning hub seems to be running with 2022.1 version, in which case that cannot be used for exploration purpose.
• Table Name is the one that will be used to create or update records into
  • The library "llama-iris" appends "data_" to the table name. So, when you are trying to check the data through DB client, append "data_" to the table name. Say, you've named table as "users", you would need to retrieve as "data_users"
• Embed Dim / Embedding Dimension is the dimension of the Embedding model that the user used
  • Say you've loaded "users" table by using OpenAI embeddings - "text-embedding-3-small" with 1536 dimension. You would be able to load more data into the table, but only with 1536 dimension. Same goes with vector embedding retrievals as well. So, make sure to choose the right model in the initial phases.

CONNECTION_STRING = f"iris://{username}:{password}@{hostname}:{port}/{namespace}"
vector_store = IRISVectorStore.from_params(
    connection_string=CONNECTION_STRING,
    table_name=table_name,
    embed_dim=embedding_dimension
)

Settings.embed_model = set_embedding_model(indexing_type, model_name, api_key)

storage_context = StorageContext.from_defaults(vector_store=vector_store)
index = VectorStoreIndex.from_documents(
    documents,
    storage_context=storage_context
)

Step 3: Loading the embedding and text into IRIS DB

The above written code covers the indexing and loading of data into IRIS DB. Here is how the data would look like - 

Text - Raw text information that's been extracted from the files we loaded

Node ID - This would be used as a reference when we do retrievals 

Embeddings - The actual numerical representations of the text data

These three steps are through which the connectors module mainly work. When it comes to required data, like DB credentials and API Keys - I get it from the user and save it to the browser's local storage (Instance Details) and session storage (API Keys). It gives more modularity to the application for anyone to explore.

By bringing together the loading of vector-embedded data from files and the retrieval of content through various channels, IRIS AI Studio enables an intuitive way to explore the Generative AI possibilities that InterSystems IRIS offers - not only for existing customers, but also for new prospects.
