KEEP_LAST=N vs KEEP_ALL + ResourceLimits.max_samples=N

Hi,

Is there any difference between those two settings for a topic with one instance?

HistoryQosPolicy.kind = KEEP_LAST_HISTORY_QOS
HistoryQosPolicy.depth = N

and

HistoryQosPolicy.kind = KEEP_ALL_HISTORY_QOS
ResourceLimitsQosPolicy.max_samples = N
ResourceLimitsQosPolicy.max_samples_pre_instance = N

Best regards,
RafaƂ
