DDSXTY12 — Send TypeId independently of the TypeObject

  • Key: DDSXTY12-2
  • Legacy Issue Number: 19262
  • Status: closed  
  • Source: Real-Time Innovations ( Sumant Tambe)
  • Summary:

    Sending large TypeObjects is often an issue in discovery. Often times, the complete TypeObjects are not necessary as TypeId might just do the trick when exact matches are expected. Therefore, sending just the typeid is a good optimization.

    Therefore, add new discovery parameter in Publication and Subscription BuiltInTopicData to send the TypeId independently of the type object.

    Two use cases:
    1. Even if we cannot find type object at least we can verify typeId
    2. Allow a separate mechanism to get the TypeObject. This will help to reduce bandwidth
