What’s new with Open Source DDS Community Edition v6.7 Software

DDS Community v6.7 Mailer Poster

PrismTech recently released its latest version of Open Source DDS Community Edition, the 6.7 version which adds significant new functionality and a new open source licensing model to the DDS Community Edition.

The DDS Community Edition v6.7 is being released to the open source community under the widely adopted Apache license, version 2.0 source code license. Unlike many other code licenses the Apache license places very few restrictions on the use or availability of the code.

Here are the new features included on this release:

  • Durability: Full support for TRANSIENT_LOCAL durability is now offered without relying on each standalone ‘single-process’ application to include a full durability-service (DS).  As typically a DS is run as part of a federation, we have introduced the concept of ‘client-side durability’ where standalone ‘single-process’ applications will transparently obtain historical data from dynamically discovered durability-services (as provided by our commercial OpenSplice version)
  • DCPS API’s: Support for the latest ISOCPP and JAVA5 DCPS language bindings
  • FACE: This release includes a reference implementation of the FACE 2.1 Transport Services Segment (TSS)
  • GPB: Support to use Google Protocol Buffers (GPB) as an alternative to the OMG-IDL definition for topic-types. GPB is a popular technology that supports evolvable data-types and we’ve added annotations for key- and filterable-fields to retain the data-centric features of DDS.

The new release also includes numerous other updates to the code base such as: performance and footprint improvements, bug fixes, robustness and maintainability improvements.

With having Apache license version 2.0 open source license available, this will help reduce the IoT adoption barriers and further accelerate the penetration of DDS in this new and exciting market.
