Hello @AayushTyagi1, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

Summary of Changes

This pull request updates the langchain-couchbase version in the RAG_with_Couchbase_and_Bedrock.ipynb notebook. The primary change involves replacing CouchbaseVectorStore with CouchbaseSearchVectorStore. Additionally, the notebook has been updated to create buckets and collections if they don't exist, and a time delay was added after bucket creation. Execution counts for code cells have been updated, and the notebook metadata now reflects Python version 3.9.6.

Highlights

• Vector Store Update: Replaced CouchbaseVectorStore with CouchbaseSearchVectorStore in the notebook.
• Bucket and Collection Creation: The notebook now creates Couchbase buckets and collections if they do not already exist.
• Environment Variables: Added instructions for setting up environment variables using .env.sample.
• Index Creation: The notebook now explicitly creates the vector search index if it doesn't exist.

Changelog

Code Review

The pull request updates the lanchain-couchbase version in the RAG example and includes several improvements, such as clarifying environment variable setup and addressing potential timing issues during bucket creation. The changes appear to be well-intentioned, but require careful review to ensure correctness and maintainability.

Summary of Findings

• Dependency Update Impact: The update to the lanchain-couchbase version introduces a change in the vector store import, replacing CouchbaseVectorStore with CouchbaseSearchVectorStore. This change could have significant implications for the existing vector search functionality and requires careful consideration to ensure compatibility and expected behavior.
• Environment Variable Setup: The addition of instructions for setting up environment variables using .env files is a good practice for managing sensitive information. However, it's crucial to ensure that the .env.sample file is comprehensive and accurately reflects all required environment variables.
• Bucket Creation Delay: The introduction of a time.sleep(2) call after bucket creation suggests a potential race condition or timing issue. While this might resolve the immediate problem, it's essential to investigate the underlying cause and consider a more robust solution, such as polling for bucket availability.

Merge Readiness

The pull request introduces important updates and clarifications to the RAG example. However, due to the potential impact of the dependency update and the use of a time.sleep call, I recommend a thorough review and testing of the changes before merging. I am unable to approve this pull request, and recommend that others review and approve this code before merging.
