- Rtm没有群的概念，频道同时只能创建20个
- 是的，你release只是release自己的channel对象并从channel离开，并不影响channel本身
- 频道消息不支持离线，点对点消息支持，离线消息的保存时间请参考文档
- 是的 如果想收对应频道的群消息，必须加入频道并监听

1.同时创建最多20个是针对单个用户而言的吧？即每个用户可同时加入或者创建总共20个频道？但总数其实是不限20个？

是的 你登入rtm后 一个session内你只能同时加入20个频道，整体频道数没有限制

明白了
1.用着实现传统群的需求是不行的，因为用户很有可能加入超过20个群，而且需要每个加入过未解散的群都能收到消息。这个限制有必要吗，可以去除吗
4._client.onMessageReceived 只能监听到点对点的消息。 channel.onMessageReceived 能监听到 channel 的消息，加入多个 channel 需要每个都绑定独立事件，但消息监听我们需要做成一个全局的 provider，实现想来会比较麻烦。如果能在_client.onMessageReceived 这个 channel 的上层监听所有的 channel 消息，只是消息类型不同感觉会好一点？

基本上RTM不是完全设计用来做IM功能的SDK，他和IM SDK还是有区别的，更多是为了和其他用户实时信号互动的作用，因此你提到的这些限制都是为了实现更低延时和更高互动性进而限制的东西
