What is the right way to praise the function?

Let's say a table userid,topicid,act, such a design I know, but if a topic like the number of hundreds of thousand that the amount of data is not too big, the general station is how to design praise. is MySQL okay?

This is what we segmentfault to deal with:

1. The subject information in the database, including the total number of likes.
2. Redis places the data that is liked, such as who has praised which topic.
