Minutes

3. take-modify-publish pipeline

• Lear Corp offers support in system testing
• Possible problem: How to transfer the ownership of a sample to another publisher if the originator has another mempool/memory segment?
• Maybe additional publisher option to allow only one subscriber?
• Design document needed
• Should history size > 1 be allowed?
• Maybe introduce a "locking" mechanism to sample for forwarding
• Create a new "exclusive" port type to explicitly forbid history to restrict the container of (subscriber)queues to capacity = 1
• not part of iceoryx 2.0

4. Enhancement of the ServiceDescription (issue needed)

• Problem: ServiceDescription needs more user-defined properties for a more fine-grained identification
• Proposal 1: Add a class with template parameter for comparison to the ServiceDescription
• Proposal 2: Replace SD with a complete user-configurable field with comparison, matching operators etc. to make it scalable
