What Is Deepstream

There are similarities that can be drawn between Deepstream and other products like Firebase, Redis, etc. Deepstream supports concepts like pub/sub, rpcs, and data-syncing. It can be considered that Deepstream acts as a message broker with a data store, however, this blog post explains the comparisons in much more detail.

Message Broker

A message broker can be defined as a physical component that handles the communication between applications. Instead of communicating with each other, applications communicate only with the message broker. An application sends a message to the message broker, providing the logical name of the receivers. The message broker looks up applications registered under the logical name and then passes the message to them. Figure 1 illustrates this configuration.

Expanding on the idea of Deepstream acting as a message broker with a data store, with this in mind, one can develop a product with multiple moving parts written in different programming languages and still have things working together. A message broker allows you to treat data and events from a language agnostic standpoint.

Data Store

Deepstream offers a in-cache data store that can hold all types of data.

  • Numbers (Integers/Doubles)
  • Strings
  • Objects
  • Lists


Deepstream offers the ability of a publish and subscribe event pattern. Clients can publish data through the deepstream system and any clients subscribed can receive that data.


Deepstream offers remote procedural call (RPC) which are equivalent to a request-response pattern.


Deepstream offers data-syncing when items/records are updated in your data store.
