Redis Get All Keys and Its Values

Storage And Backup
#1

I am aware that in order to get all the keys in Redis, I have to use KEYS *, but is there a way to output all keys along with their values?

You can use MGET to get the values of multiple keys in a single go.

Example:

redis> SET key1 "Hello"
"OK"
redis> SET key2 "World"
"OK"
redis> MGET key1 key2 nonexisting
1) "Hello"
2) "World"
3) (nil)

For listing out all keys & values you’ll probably have to use bash or something similar, but MGET can help in listing all the values when you know which keys to look for beforehand.

One can put the below script in a file and execute to get the desired result ,

#!/bin/bash

# Default to '*' key pattern, meaning all redis keys in the namespace
REDIS_KEY_PATTERN="${REDIS_KEY_PATTERN:-*}"
for key in $(redis-cli --scan --pattern "$REDIS_KEY_PATTERN")
do
    type=$(redis-cli type $key)
    if [ $type = "list" ]
    then
        printf "$key => \n$(redis-cli lrange $key 0 -1 | sed 's/^/  /')\n"
    elif [ $type = "hash" ]
    then
        printf "$key => \n$(redis-cli hgetall $key | sed 's/^/  /')\n"
    elif [ $type = "smembers" ]
    then
        printf "$key => $(redis-cli smembers $key)\n"
    elif [ $type = "zset" ]
    then
        printf "$key => $(redis-cli zrange $key 0 -1)\n"
    elif [ $type = "set" ]
    then
        printf "$key => $(redis-cli smembers $key)\n"
    else
        printf "$key => $(redis-cli get $key)\n"

    fi
done

Output:
