New Realtime Messaging Features with Diffusion 5.7
June 14, 2016 | DiffusionData
JSON/Binary Delta Streaming
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.
- 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.
