What should I do if I use the apsaradb for memcache environment?

For the use environment of memcache, I would like to ask some scenarios of memcache. I also want to know what data is used and what data is used in redis. this is generally applicable to systems with data of more than 100,000, to be used. As for what data to use, you need to check what data cache you need. The difference between memcache and redis lies in persistence and the use environment of memcache in other zones.

In other words, redis also asks which data is easy to use.
------ Solution --------------------
It is generally applicable to systems with a data volume of more than 100,000.
As for what data to use, you need to check what data cache you need.
The difference between memcache and redis lies in persistence.
So if you use redis, it depends on whether your business needs a longer data storage period?
