| If the ''DataWriter'' objects are communicating [[dido:public:ra:xapend:xapend.a_glossary:s:sample|samples]] faster than they are ultimately taken by the ''DataReader'' objects, the [[dido:public:ra:xapend:xapend.a_glossary:m:midware|middleware]] will eventually hit against some of the QoS-imposed resource limits. Note that this may occur when just a single ''DataReader'' cannot keep up with its corresponding ''DataWriter''. The behavior in this case depends on the setting for the RELIABILITY QoS. If reliability is BEST_EFFORT then the Service is allowed to drop samples. If the reliability is RELIABLE, the Service will block the ''DataWriter'' or discard the sample at the ''DataReader'' 28in order not to loose existing samples. | If the ''DataWriter'' objects are communicating [[dido:public:ra:xapend:xapend.a_glossary:s:sample|samples]] faster than they are ultimately taken by the ''DataReader'' objects, the [[dido:public:ra:xapend:xapend.a_glossary:m:midware|middleware]] will eventually hit against some of the QoS-imposed resource limits.
