Realtime features
Pub/Sub messaging Pub/Sub is a design pattern that lets any number of publishers (producers) push messages to channels (also known as topics). Multiple subscribers (consumers) can subscribe to a channel to consume published messages.	Explore Ably's pub/sub messaging implementation
Message queues A message queue is a form of asynchronous service-to-service communication. Messages are stored on a queue until they are processed. Note that each message is only consumed by one subscriber (consumer).	Explore Ably's message queues implementation
Presence Presence enables you to track the online and offline status of devices and end-users in real time and to store their state. Essential for chat apps and multiplayer games.	Explore Ably's presence implementation
Message history Message history provides a means to retrieve previously published messages. For this to be possible, message data must be stored (persisted) somewhere.	Explore Ably's message history implementation	Unknown
Connection state recovery (stream resume) In the case of unreliable network conditions, clients may suddenly disconnect.Connection state recovery ensures that when they reconnect, the data stream resumes exactly where it left off.	Explore Ably' s connection state recovery implementation
Guaranteed message ordering Ordering ensures that messages are delivered to consumers in the same order that producers publish them.	Explore Ably' s guaranteed message ordering implementation	Limited There’s EntityManager.saveChanges that you can call multiple times to force Breeze to save a set of entities in the backend database in the same order as they appear.
Exactly-once semantics Exactly-once is a system-wide data integrity guarantee that ensures each message is delivered to consumers exactly-once.	Explore Ably' s idempotent publishing implementation
Message delta compression Message delta compression enables you to only send the changes from the previous message to subscribers each time there’s an update, instead of the entire message. Useful for use cases where there is a significant degree of similarity between successive messages.	Explore Ably' s message delta compression implementation
Native push notifications Native push notifications can be used to deliver messages even when clients are offline. Useful for geolocation updates or news alerts.	Explore Ably's push notifications implementation
Webhooks Webhooks provide a mechanism to get messages and other types of events (such as clients entering or leaving channels) pushed to your servers over HTTP.	Explore Ably's webhooks implementation
Serverless functions A serverless function is essentially an isolated, single-purpose piece of code that is only executed when it’ triggered by an event. For example, you can use serverless functions to send a welcome message to clients when they become present on chat channels. Note that serverless functions are usually fully managed by cloud vendors.	Ably is integrated with most serverless functions providers. We support AWS Lambda, Azure Functions, Google Cloud Functions, IFTTT, Cloudflare Workers, and Zapier. Explore Ably's serverless functions implementation
Built-in integrations Which popular services & systems are Ably and Breeze integrated with?

Known limits and constraints Find out practical limits, such as the maximum message size, or the maximum number of concurrent connections.	Channel throughput: Up to 200 messages per second per outbound connection Message size limits: 16KB for free accounts and 64KB for paid accounts. For enterprise accounts, the limit can be increased to 256KB. Maximum number of channels: Limitless - constrained only by quota Maximum number of concurrent connections: Limitless - constrained only by quota Explore the practical limits of the Ably pub/sub messaging platform	Publisher throughput Unknown Maximum message size Unknown Maximum number of topics Unknown Maximum number of connections Unknown

Security
API key authentication The simplest way to authenticate. Involves using private API keys that you can usually create and edit via a dashboard. Recommended to be used server-side, as private API keys shouldn’t be shared with untrusted parties.	Explore Ably's implementation of API key authentication
Token-based authentication Which popular token-based authentication mechanisms do Ably and Breeze support? Note that token-based authentication is usually the recommended strategy on the client-side as it provides more fine-grained access control and limits the risk of credentials being compromised.
