Using custom payload pool from DDS layer

[OhadMeir]

Hi, I want to receive large messages from a UDP transport

As I understand there are 2 copies of the data:

1. From the network stack to the DataReaderHistory
2. From the history to the user

The second copy can be avoided by using loans (example), but it is not enough in my use case - a library that needs to copy the data to user provided buffers.

I want to copy directly to the user buffers by using a custom payload pool (see here) but I can't find the way to pass that pool to the DDS DomainParticipant/Subscriber/DataReader.

Is it possible to use custom IPayloadPool implementations while using DDS and not creating the RTPSReader directly?

Thanks
Ohad

@OhadMeir This is currently not possible, but would indeed be a nice addition to the API.

I have moved the discussion into the Ideas category, where we are keeping all feature requests.
