通过前面多篇文章，nsqlookupd基本已经解读完毕了，不过在关于channel和topic的增删上还比较模糊，所以本篇将站在宏观的角度来总结一下，tcp.go和http.go两个文件中关于channel和topic的操作有哪些。

总结如下表：

模块	文件	所在方法名	调用方法	Registration
模块	文件	所在方法名	调用方法	Category	Key	SubKey
TCP	lookup_protocol_v1.go	REGISTER	AddProducer	“channel”	topic	channel
		REGISTER	AddProducer	“topic”	topic	“”
		UNREGISTER	RemoveProducer	“channel”	topic	channel
			RemoveProducer	“channel”	topic	“*”
			RemoveProducer	“topic”	topic	“”
		IDENTIFY	AddProducer	“client”	“”	“”
HTTP	http.go	topicsHandler	FindRegistrations	“topic”	“*”	“”
		channelsHandler	FindRegistrations	“channel”	topicName	“*”
		lookupHandler	FindRegistrations	“channel”	topicName	“*”
		lookupHandler	FindRegistrations	“topic”	topicName	“”
		createTopicHandler	AddRegistration	“topic”	topicName	“”
		deleteTopicHandler	RemoveRegistration	“channel”	topicName	“*”
		deleteTopicHandler	RemoveRegistration	“topic”	topicName	“”
		tombstoneTopicProducerHandler	FindProducers	“topic”	topicName	“”
		createChannelHandler	AddRegistration	“channel”	topicName	channelName
		createChannelHandler	AddRegistration	“topic”	topicName	“”
		deleteChannelHandler	RemoveRegistration	“channel”	topicName	channelName
		nodesHandler	FindProducers	“client”	“”	“”
			LookupRegistrations	“topic”	“*”	“”
