Derived from [RMW Proposal] Content Filtered Topic Suport

Content Filtering Subscription is available on rolling. (and will be on humble)

https://docs.ros.org/en/rolling/Tutorials/Content-Filtering-Subscription.html#content-filtering-subscription

We are and will be working on some follow-ups, feedbacks are really welcome!!!

With Content Filtering Subscription

  • we can content-based subscription. (we can only receive the messages we need.)
  • we can save the network resource. (we can send the messages to someone needs to receive.)
  • we can have much more efficient filtering compared to filtering messages in user application. (Content Filtering Subscription happens in underlying rmw implementation w/o de-serialization, executor and so on.)

we have a good demo Temperature filtering demo, that helps us to see what’s in it for us.

thanks,
Tomoya
