Hello,
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:
KEEP_LAST_HISTORY_QOS 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.
