Redis 4.x Cookbook

How to do it

To show how to use the correct Redis APIs, the steps are as following:

1. At the beginning of this example, we will import the data from 1 million users into a hash key in Redis with two APIs: HSET and HMSET. For better illustration, we execute the following script, which connects to the Redis Server and populates the user data on another host, which is considered an application server. You may have to wait for quite a long time, so run this script and then take a break and get back to catch the result:

$ cat hmset-vs-hset.sh  
#!/bin/bash 
HSETFILE="hset.cmd" 
HMSETFILE="hmset.cmd" 
 
rm $HSETFILE $HMSETFILE 
 
... (omit all the variables declared above)printf "hmset \"user\" " >> $HMSETFILEfor i in `seq -f "%010g" 1 1000000` do namerand=$[ ...
