# Group モジュール

## 概要

Group は多数のユーザーが多方向に通信するグループを構築するのに適しています。異なるネットワーク・プロトコルを持つユーザーを接続でき、接続できるユーザー数に制限はありません。

大人数が参加するリアルタイムなメッセージの送受信に適しています。

ただし、参加人数に制限がないため、高頻度に多くのユーザーがデータを送信するような実装をした場合、意図せずサーバーとクライアントの負荷が高くなる可能性があります。

また、Group はサーバー間通信を利用して大人数とコミュニケーションを取るという性質上、同じサーバー内でコミュニケーションを取る Room と比べて RTT は高くなる傾向にあります。

## 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://help.diarkis.io/diarkis-modules/group.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.
