Probably more of a @m-hulbert question - but do we want to be calling out billing dimensions explicitly in the guide because if they ever change we have to go and update everywhere?

I would avoid talking about pricing explicitly. We can add a link to the pricing price, or to the future chat-specific pricing documentation.

## Push notifications

Ably Pub/Sub channels can be used for push notifications. See the [Push notifications](/docs/push/publish) documentation for more details. Since Ably Chat rooms are backed by a single Ably Pub/Sub channel, you can use the same channel for push notifications to notify all participants in the room when something happens.

We need to check the implications on mutable messages of using the same channel for push notifications

I've had a go with this and found it difficult to use actually:

  • chat channels require identified publishes so servers will have to set a clientId for sending push notifications
  • I found setting up push notifications to be very confusing and difficult to just reset and start over (I'm probably missing something here)

maybe we should just suggest to use another channel, or I can dig some more into this?

Regarding identified client, the web UI in the dashboard also fails to send notifications for chat channels, greeting users with this

Yeah the Web UI is a known issue that I've raised. Having to set a clientId for push notifications isn't the end of the world - but im thinking like will they be in the channel history etc

  • they show in history, but they show in history anyway if you have history enabled (not just on chat channel or mutable messages channel)
  • on mutable channels they can also be edited and deleted

Given that they show in history if you enable persistence, is this a problem?

I find "1:1 or small group" chat experience more understandable than "task-oriented".


Delivering chat messages in realtime is key to a smooth online experience. Ably's [serverless architecture](/docs/platform/architecture) eliminates the need for you to manage websocket servers. It automatically scales to handle millions of concurrent connections without provisioning or maintenance. Ably also handles all of the edge-cases around delivery, failover and scaling.

Despite the challenges of delivering these guarantees, Ably is designed to keep costs predictable.

We've done that in the livestream guide - and I think it does have a place here. But I think it should be limited to "consumption based helps if your app is like ABC, MAU helps if your app is like XYZ" - so much more of highlighting a decision point and showing how Ably works for you, rather than breaking down the pricing in detail.

I think they're probably best via a message that gets annotations for votes, but I guess it depends.

As far as I know LO are good if the state you want to track is per-room/channel and you want to keep it synched. Topic, room reactions type of thing, pinned messages, etc.

For task-oriented it can be things like the actual listing in a marketplace can be a live object if it's something that gets updated live. Or if you do a live fundraiser and you count and show how many donated and total amount raised.

I guess the status updates/progress indicator it s good one in this list

Ably's [fault tolerance guide](/docs/platform/architecture/fault-tolerance) describes how we do this and that, even if an entire region
goes down, it has little-to-no impact on the global service and your application.

Keep or drop?

### Aggressive connection management

When a client abruptly disconnects from Ably, there is a 2 minute delay before the connection is cleaned up on the server, to enable the client to resume the connection from where it left off. When you're finished with an Ably connection, be sure to call the `close()` method to gracefully shut down the connection.

Last things to decide:

  1. Entirely drop pricing section or keep it? I've removed a few mentions of pricing but there was some duplication.
  2. Push notifications thread
  3. "Engaging experience" wording

  1. I think we need to talk about how Ably's pricing works for you calling out the key wins, but just avoiding detailed breakdown.
  2. It's not currently possible to send push notifications via Chat directly (as you can't set the extras payload without Pub/Sub), so we should decide whether we tell people about how to send PN's via a correctly-formatted pubsub message on the chat channel, or as a message on a separate channel / direct publish.
  3. Suggestion works for me.

Per-attachment rate limits aren't helpful for Chat in many scenarios because we publish via REST.


In task-oriented chat, each room is typically low throughput. Scaling comes by running as many rooms as you need at the same time. Ably handles everything from 1:1 conversations and small group discussions to [livestream chats](/docs/guides/chat/build-livestream) with the same reliability and scalability guarantees.

I think this section needs to come across more as "here are some things you need to think about" rather than suggesting we have solutions right now for them (attachment rate limits aren't really helpful and the global limits aren't really the right fit).

If you look at the livestreaming guide, we've framed it more as a discussion of things you need to think about and decisions you need to make.

I guess it raises the question - is throughput / rate management the best fit for these types of chats?
