when i start a redis replication with one master and two slaves,i find that mset command cannot be sync well. eg.with redis-py >>>dda='{"contact": {"mobile": 134023424, "tel": 2384242}, "name": "tom"}' >>>ddb='{"contact": {"mobile": 139763224, "tel": 6534242}, "name": "john"}' >>>master.mset({'dda':dda,'ddb':ddb}) >>>slave.get('dda') >>>'{"contact": {"mobile": 134023424, "tel": 2384242}, "name": "tom"}' >>>slave.get('ddb') >>>'{"contact":'

so mset can not be sync fully. why and some solutions?
