Issue 16954: Remove the concept of Topic Kinds (With Key vs. No Key) (data-distribution-interop-rtf)
Source: OCI (Mr. Adam Mitz, mitza(at)ociweb.com)
Nature: Uncategorized Issue
Severity: 
Summary: This distinction is important for DDS, but not relevant for RTPS.  There are places where RTPS deals with the Key as an independent unit of data (KeyFlag, etc.), but those are not relevant to the TopicKind_t which seems to be an artifact of an older version of the specification.  The current protocol as written in this specification works the same way for both With Key and No Key topics.  This issue seeks to remove the Topic Kind concept entirely from the specification.

Remove the concept of Topic Kinds (With Key vs. No Key)
