Redis-Dump 介绍
Redis-Dump
是一个将Redis数据导入/导出为json格式数据的小工具，目前还在Alpha版本，目前提供两个命令，将Redis数据层出成json的redis-
dump命令，以及将json文件导入到redis中的redis-load命令，喜欢尝鲜的同学可以试玩一下。
另外个人认为这也是一个适合新手的Redis数据结构学习工具，通过将Redis几种数据结构dump成json，可以让我们更直观的认识Redis数据结构及其操作。
下面是使用简介：
$ redis-dump $ redis-dump -u 127.0.0.1:6371 > db_full.json $ redis-dump -u 127.0.0.1:6371 -d 15 > db_db15.json $ < db_full.json redis-load $ < db_db15.json redis-load -d 15 # OR $ cat db_full | redis-load $ cat db_db15.json | redis-load -d 15 # You can specify the redis URI via an environment variable $ export REdis_URI=127.0.0.1:6371 $ redis-dump
层出的json数据格式如下，包括了db，key，ttl，数据的type，以及相应的数据
{"db":0,"key":"hashkey","ttl":-1,"type":"hash","value":{"field_a":"value_a","field_b":"value_b","field_c":"value_c"},"size":42}
{"db":0,"key":"listkey","ttl":-1,"type":"list","value":["value_0","value_1","value_2","value_0","value_1","value_2"],"size":42}
{"db":0,"key":"setkey","ttl":-1,"type":"set","value":["value_2","value_0","value_1","value_3"],"size":28}
{"db":0,"key":"zsetkey","ttl":-1,"type":"zset","value":[["value_0","100"],["value_1","100"],["value_2","200"],["value_3","300"],["value_4","400"]],"size":50}
{"db":0,"key":"stringkey","ttl":79,"type":"string","value":"stringvalue","size":11}
