Regulate sample traffic with datareader QoS


I have a writer publishing a lot of topic instances (> 100 000), one sample per instance.

I want a late joining reader (or several) to get the last sample of each instances from the writer history.

I don't want the writer to block when writing samples.

I set the QoS for both datareader and datawriter:

depth = 1

When the reader starts, all the samples are sent on the wire from the writer to the reader, leading to a huge peak in the flow of UDP packets.
