# Values With Subkeys

### Values with subkeys

The Subnet DHT also supports a special value type that is itself a dictionary. When nodes store such a value, they add subkeys to the dictionary instead of overwriting it.

Consider an example where three DHT nodes want to find out who is going to attend the party:

```python
alice_dht = DHT(initial_peers=dht.get_visible_maddrs(), start=True)
bob_dht = DHT(initial_peers=dht2.get_visible_maddrs(), start=True)
carol_dht = DHT(initial_peers=alice_dht.get_visible_maddrs(), start=True)


# first, each peer stores a subkey for the same key
alice_dht.store('party', subkey='alice', value='yes', expiration_time=get_dht_time() + 600)
bob_dht.store('party', subkey='bob', value='yes', expiration_time=get_dht_time() + 600)
carol_dht.store('party', subkey='carol', value='no', expiration_time=get_dht_time() + 600)

# then, any peer can get the full list of attendees
attendees, expiration = alice_dht.get('party', latest=True)
print(attendees)
# {'alice': ValueWithExpiration(value='yes', expiration_time=1625504352.2668974),
#  'bob': ValueWithExpiration(value='yes', expiration_time=1625504352.2884178),
#  'carol': ValueWithExpiration(value='no', expiration_time=1625504352.3046832)}
```

When running over the Internet, some `dht.get/store` requests may run for hundreds of milliseconds and even seconds. To minimize the wait time, you can call these requests asynchronously via [`dht.store/get/run_coroutine(..., return_future=True)`](/subnet-template/dht.md#get-key-any-latest-bool-false-return_future-bool-false-kwargs-union-valuewithexpiration-any-none-mpf) . This will run the corresponding command in the background and return a [Future-like](https://docs.python.org/3/library/concurrent.futures.html) object that can be awaited. Please also note that the returned future is compatible with asyncio (i.e., can be awaited inside the event loop).

For more details on DHT store/get and expiration time, please refer to the [documentation for DHT and DHTNode](/subnet-template/dht.md#dht-and-dhtnode).

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.hypertensor.org/subnet-template/quick-starts/values-with-subkeys.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
