Summary of Changes
Hello @mostafaalaa3, 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!
This pull request updates the session_sample.py file to migrate from using the ConversationalSearchServiceClient to the new SessionServiceClient. This change is proactive, as the former client is slated for deprecation, ensuring the sample remains current and functional with the recommended API client. The new client is noted to have the exact same methods as the one it replaces, simplifying the transition.
Highlights
- Client Migration: The
discoveryengine.ConversationalSearchServiceClientclient instantiation has been replaced withdiscoveryengine.SessionServiceClientin all five session-related functions (create_session,get_session,delete_session,update_session,list_sessions) withinsession_sample.py.

Code Review
This pull request correctly updates the deprecated ConversationalSearchServiceClient to SessionServiceClient as intended. The change is straightforward. My review includes one suggestion to improve the sample code by adding a comment about client instantiation best practices. While the current approach is fine for self-contained examples, it's important to guide users on efficient client reuse in real-world applications. This will help prevent performance issues for users who adapt this sample code.

Instantiating a new client for each function call is not a recommended practice for production applications. Google Cloud client libraries are designed to have their client instances reused to avoid the overhead of setting up new connections for each request.
While this pattern is acceptable for a self-contained sample where each function is independent, adding a comment to educate users about this best practice would be very helpful.
This feedback also applies to the other functions in this file where a client is instantiated (lines 74, 107, 141, and 181).
| client = discoveryengine.SessionServiceClient() | |
| # In real-world applications, a single client instance should be created and reused for better performance. | |
| client = discoveryengine.SessionServiceClient() |

This obviously requires the a new client to be used |
feat: Update session sample with the new SessionServiceClient instead of ConversationalSearchServiceClient.
Description
ConversationalSearchServiceClient will be deprecated soon and we would like to use SessionServiceClient instead. The new service has the exact same methods as the previous one.
