Are data samples queued and if so, where?

My understanding is that DDS DataWriters communicate CacheChanges to the HistoryCaches of the associated RTPS Writer. This CacheChange is then propagated to the mapped RTPS Readers before notifying their associated DDS DataReaders.

From the above statement, there are queues (the HistoryCache) on the RTPS Writers and Readers.

Publishing only the changed fields

Hi all,

I'm wondering if there is a way to write only a member subset of a complex type so that, for instance, I could send those members whose value has changed.

Thanks

Antonio
