Diffusion 5.7, a market-proven realtime messaging platform designed for enterprise, has just been released. Find out what’s new so you can benefit from efficient realtime data distribution that optimizes data delivery for your web, mobile and IoT apps. The latest features include JSON/binary delta streaming and enhanced information security. The patent-pending features make live data subscription streams possible for JSON/binary deltas, offer native JavaScript support and enable granular access controls for applications, users and data objects.

JSON/Binary Delta Streaming

JSON (JavaScript Object Notation) may offer much improved data efficiency over its predecessors (such as XML), but the attribute markup still represents significant overhead on the wire.

Push Technology’s delta streaming feature provides clients only the differences between old and new data, rather than providing the entire JSON payload – limiting the need to send markup that isn’t changing from one message to the next.

The Java™, JavaScript^®, .NET, and Android™ Unified API clients provide the ability to create, update, and subscribe to JSON and binary topics.

• JSON topics enable you to structure your data using JSON. The data is transmitted in a Concise Binary Object Representation (CBOR) binary form for increased efficiency. For more information, see JSON topics.

• Binary topics enable you to stream your data in pure binary form without the overhead of having to encode the binary data into string form. For more information, see Binary topics.

Role-based Access Control for Enhanced Information Security

Diffusion 5.7 offers granular management for each data resource. The configurable topic-scoped permissions and session properties allow backend developers to enable application, user and data level controls across data access. Organizations gain highly configurable security and effective data flow governance helping to defend against unauthorized access, use, disclosure, modification, inspection, recording or destruction of data.

The select_topic security permission has been added to the list of topic-scoped permissions. This permission controls whether sessions can subscribe to or fetch from particular parts of the topic tree. For more information, see Permissions.

If you are upgrading an existing configuration to work with Diffusion 5.7, update your Security.store file to grant this new permission to the appropriate roles. For more information, see Upgrading from version 5.6 to version 5.7.
