# Conversation & Session Management Samples
|
|
|
|
These samples demonstrate different approaches to managing conversation history and session state in Agent Framework.
|
|
|
|
## Samples
|
|
|
|
| File | Description |
|
|
|------|-------------|
|
|
| [`suspend_resume_session.py`](suspend_resume_session.py) | Suspend and resume conversation sessions, comparing service-managed sessions (Azure AI Foundry) with in-memory sessions (OpenAI). |
|
|
| [`custom_history_provider.py`](custom_history_provider.py) | Implement a custom history provider by extending `HistoryProvider`, enabling conversation persistence in your preferred storage backend. |
|
|
| [`file_history_provider.py`](file_history_provider.py) | Use the experimental `FileHistoryProvider` with `FoundryChatClient` and a function tool so the local JSON Lines file shows the full tool-calling loop. |
|
|
| [`file_history_provider_conversation_persistence.py`](file_history_provider_conversation_persistence.py) | Persist a tool-driven weather conversation with `FileHistoryProvider`, inspect the stored JSONL records, and continue with another city. |
|
|
| [`cosmos_history_provider.py`](cosmos_history_provider.py) | Use Azure Cosmos DB as a history provider for durable conversation storage with `CosmosHistoryProvider`. |
|
|
| [`cosmos_history_provider_conversation_persistence.py`](cosmos_history_provider_conversation_persistence.py) | Persist and resume conversations across application restarts using `CosmosHistoryProvider` — serialize session state, restore it, and continue with full Cosmos DB history. |
|
|
| [`cosmos_history_provider_messages.py`](cosmos_history_provider_messages.py) | Direct message history operations — retrieve stored messages as a transcript, clear session history, and verify data deletion. |
|
|
| [`cosmos_history_provider_sessions.py`](cosmos_history_provider_sessions.py) | Multi-session and multi-tenant management — per-tenant session isolation, `list_sessions()` to enumerate, switch between sessions, and resume specific conversations. |
|
|
| [`redis_history_provider.py`](redis_history_provider.py) | Use Redis as a history provider for persistent conversation history storage across sessions. |
|
|
|
|
## Prerequisites
|
|
|
|
**For `suspend_resume_session.py`:**
|
|
- `FOUNDRY_PROJECT_ENDPOINT`: Your Azure AI Foundry project endpoint (service-managed session)
|
|
- `FOUNDRY_MODEL`: The Foundry model deployment name
|
|
- `OPENAI_API_KEY`: Your OpenAI API key (in-memory session)
|
|
- Azure CLI authentication (`az login`)
|
|
|
|
**For `custom_history_provider.py`:**
|
|
- `OPENAI_API_KEY`: Your OpenAI API key
|
|
|
|
**For `file_history_provider.py`:**
|
|
- `FOUNDRY_PROJECT_ENDPOINT`: Your Azure AI Foundry project endpoint
|
|
- `FOUNDRY_MODEL`: The Foundry model deployment name
|
|
- Azure CLI authentication (`az login`)
|
|
- The sample writes plaintext JSONL conversation logs to disk; use a trusted
|
|
local directory and avoid treating the history files as secure secret storage
|
|
|
|
**For `file_history_provider_conversation_persistence.py`:**
|
|
- `FOUNDRY_PROJECT_ENDPOINT`: Your Azure AI Foundry project endpoint
|
|
- `FOUNDRY_MODEL`: The Foundry model deployment name
|
|
- Azure CLI authentication (`az login`)
|
|
- The sample writes plaintext JSONL conversation logs to disk; use a trusted
|
|
local directory and avoid treating the history files as secure secret storage
|
|
|
|
**For Cosmos DB samples (`cosmos_history_provider*.py`):**
|
|
- `FOUNDRY_PROJECT_ENDPOINT`: Your Azure AI Foundry project endpoint
|
|
- `FOUNDRY_MODEL`: The Foundry model deployment name
|
|
- `AZURE_COSMOS_ENDPOINT`: Your Azure Cosmos DB account endpoint
|
|
- `AZURE_COSMOS_DATABASE_NAME`: The database that stores conversation history
|
|
- `AZURE_COSMOS_CONTAINER_NAME`: The container that stores conversation history
|
|
- Either `AZURE_COSMOS_KEY` or Azure CLI authentication (`az login`)
|
|
|
|
**For `redis_history_provider.py`:**
|
|
- `OPENAI_API_KEY`: Your OpenAI API key
|
|
- A running Redis server — default URL is `redis://localhost:6379`
|
|
- Override via the `REDIS_URL` environment variable for remote or authenticated instances
|
|
- Quickstart with Docker: `docker run -d --name redis-stack -p 6379:6379 redis/redis-stack-server:latest`
