## AsyncMemory

The `AsyncMemory` class is a direct asynchronous interface to Mem0's in-process memory operations. Unlike the memory, which interacts with an API, `AsyncMemory` works directly with the underlying storage systems. This makes it ideal for applications where you want to embed Mem0 directly into your codebase.

### Initialization

To use `AsyncMemory`, import it from the `mem0.memory` module:

```python Python
import asyncio
from mem0 import AsyncMemory

# Initialize with default configuration
memory = AsyncMemory()

# Or initialize with custom configuration
from mem0.configs.base import MemoryConfig
custom_config = MemoryConfig(
    # Your custom configuration here
)
memory = AsyncMemory(config=custom_config)
```

### Key Features

1. **Non-blocking Operations** - All memory operations use `asyncio` to avoid blocking the event loop
2. **Concurrent Processing** - Parallel execution of vector store and graph operations
3. **Efficient Resource Utilization** - Better handling of I/O bound operations
4. **Compatible with Async Frameworks** - Seamless integration with FastAPI, aiohttp, and other async frameworks

### Methods

All methods in `AsyncMemory` have the same parameters as the synchronous `Memory` class but are designed to be used with `async/await`.

#### Create memories

Add a new memory asynchronously:

```python Python
await memory.add(
    messages=[
        {"role": "user", "content": "I'm travelling to SF"},
        {"role": "assistant", "content": "That's great to hear!"}
    ],
    user_id="alice"
)
```

#### Retrieve memories

Retrieve memories related to a query:

```python Python
await memory.search(
    query="Where am I travelling?",
    user_id="alice"
)
```

#### List memories

List all memories for a `user_id`, `agent_id`, or `run_id`:

```python Python
await memory.get_all(user_id="alice")
```

#### Get specific memory

Retrieve a specific memory by its ID:

```python Python
await memory.get(memory_id="memory-id-here")
```

#### Update memory

Update an existing memory by ID:

```python Python
await memory.update(
    memory_id="memory-id-here",
    data="I'm travelling to Seattle"
)
```

#### Delete memory

Delete a specific memory by ID:

```python Python
await memory.delete(memory_id="memory-id-here")
```

#### Delete all memories

Delete all memories for a specific user, agent, or run:

```python Python
await memory.delete_all(user_id="alice")
```

Note: At least one filter (user_id, agent_id, or run_id) is required when using delete_all.

#### Memory History

Get the history of changes for a specific memory:

```python Python
await memory.history(memory_id="memory-id-here")
```

### Example: Concurrent Usage with Other APIs

`AsyncMemory` can be effectively combined with other async operations. Here's an example showing how to use it alongside OpenAI API calls in separate threads:

```python Python
import asyncio
from openai import AsyncOpenAI
from mem0 import AsyncMemory

async_openai_client = AsyncOpenAI()
async_memory = AsyncMemory()

async def chat_with_memories(message: str, user_id: str = "default_user") -> str:
    # Retrieve relevant memories
    search_result = await async_memory.search(query=message, user_id=user_id, limit=3)
    relevant_memories = search_result["results"]
    memories_str = "\n".join(f"- {entry['memory']}" for entry in relevant_memories)
    
    # Generate Assistant response
    system_prompt = f"You are a helpful AI. Answer the question based on query and memories.\nUser Memories:\n{memories_str}"
    messages = [{"role": "system", "content": system_prompt}, {"role": "user", "content": message}]
    response = await async_openai_client.chat.completions.create(model="gpt-4o-mini", messages=messages)
    assistant_response = response.choices[0].message.content

    # Create new memories from the conversation
    messages.append({"role": "assistant", "content": assistant_response})
    await async_memory.add(messages, user_id=user_id)

    return assistant_response

async def async_main():
    print("Chat with AI (type 'exit' to quit)")
    while True:
        user_input = input("You: ").strip()
        if user_input.lower() == 'exit':
            print("Goodbye!")
            break
        response = await chat_with_memories(user_input)
        print(f"AI: {response}")

def main():
    asyncio.run(async_main())

if __name__ == "__main__":
    main()
```
