As The Who sang in their 1971 hit, we are “Going Mobile”. No, RTI is not moving its engineers to camper vans, we are referring to an exciting feature available in the newly released ConnextⓇ DDS 5.3!
It is not always practical, or even possible, for an application to know what subset of data it will need access to as that data is being published. For example, imagine an application that subscribes to one subset of data during normal operating conditions, but then after an alarm is triggered all data from the past 24 hours is required. Does it make sense for the subscribing application to receive all data at all times just in case the alarm sounds, taking up bandwidth and resources in the subscribing application? Or does it make more sense for the subscribing application to be able to request the data it needs at the moment it needs it, saving bandwidth and resources in the common case? The second option is the most obvious choice, right? We thought so too, which is why with the introduction of Topic Queries in RTI Connext DDS 5.3.0, we allow DataReaders to do just that – send a request to all matching DataWriters for historical data that matches a given filter expression.
RTI Connext DDS 5.3.0 is now live! I’m really excited to be back with a new blog post about one of the key new features of this release: the RTI Security Plugins. The reason I’m so excited about this one it is because this is our first release that is fully wire-compliant with the OMG DDS Security specification.
If you are looking for a high-level overview of OMG’s DDS Security specification, or you are wondering how can you can get started using it in your application, you are in the right place.
On behalf of everyone at RTI, I am proud to announce the general availability of Connext DDS 5.3: the first connectivity software for architecting Industrial Internet of Things (IIoT) systems of systems!
In this release of Connext DDS, we are launching several features designed to help our customers build secure and scalable systems reflective of the layered-databus architecture using the Connext Databus. Let’s tour these features and apply them to the layered-databus architecture as well as to actual industries implementing these architectural patterns using our technology.
