What separates DDS from other publish-subscribe middleware?

Hi!

Very quick question:

What separates DDS from other publish-subscribe middleware? What makes it unique from other publish-subscribe middleware?

Thanks,

Kaleem

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.
