Better Performance hget vs get || Using Redis
1>
hset key field value ---Here field("dept") will always be same(constant) and key could be 20 char
hset "user1" "dept" 1
hset "user2" "dept" 2
hset "user3" "dept" 2
2>
set key value --Here key could be 20 char
set "{user1}dept" 1
set "{user2}dept" 2
set "{user3}dept" 3
Q1.
In both cases which get cmd will run faster (considering our database has millions of key value pair)
hget "user2" "dept" vs get "user2" "dept"
Q2. is hset "user1" "dept" 1 is equivalent to {"user1" : {"dept" : 1}} or {"dept" : {"user1" : 1}}
Q3. I want to implement expiry on key and field which is not possible in case of hset is there any alternative?
