Redis-Dump將?Redis?數(shù)據(jù)導(dǎo)入/導(dǎo)出為 json 格式數(shù)據(jù)

Redis-Dump 是一個(gè)將 Redis 數(shù)據(jù)導(dǎo)入/導(dǎo)出為 json 格式數(shù)據(jù)的小工具，目前還在Alpha版本，目前提供兩個(gè)命令，將Redis數(shù)據(jù)層出成json的redis-dump命令，以及將json文件導(dǎo)入到redis中的redis-load命令，喜歡嘗鮮的同學(xué)可以試玩一下。

另外個(gè)人認(rèn)為這也是一個(gè)適合新手的Redis數(shù)據(jù)結(jié)構(gòu)學(xué)習(xí)工具，通過將Redis幾種數(shù)據(jù)結(jié)構(gòu)dump成json，可以讓我們更直觀的認(rèn)識(shí)Redis數(shù)據(jù)結(jié)構(gòu)及其操作。

下面是使用簡(jiǎn)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

層出的json數(shù)據(jù)格式如下，包括了db，key，ttl，數(shù)據(jù)的type，以及相應(yīng)的數(shù)據(jù)

{"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}
