Better Performance hget vs get || Using Redis
问题
以下是翻译好的内容：
更好的性能 hget vs get || 使用 Redis
1>
hset key field value ---这里的 field("dept") 将始终是相同的（常量），而 key 可能是20个字符
hset "user1" "dept" 1
hset "user2" "dept" 2
hset "user3" "dept" 2
2>
set key value --这里的 key 可能是20个字符
set "{user1}dept" 1
set "{user2}dept" 2
set "{user3}dept" 3
Q1.
在这两种情况下，哪个 get cmd 将运行得更快（考虑我们的数据库有数百万个键值对）
hget "user2" "dept" vs get "user2" "dept"
Q2. hset "user1" "dept" 1 是否等同于 { "user1" : { "dept" : 1 }} 或者 { "dept" : { "user1" : 1 }}？
Q3. 我想在 key 和 field 上实现过期，但在使用 hset 的情况下似乎不可能，有没有其他的替代方法？
英文:
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?
