How to make a video view counter?

Question

PostgreSQL

How to make a video view counter using a database, but so that if several people watched the video at one moment, all these views were taken into account, and there was no such situation that 5 people watched the video at one moment, and because of the time to change the value of views in bd, 5 views counted as one. I know about locks in the database, but they slow down the work at times (in this case, 5 times), especially since the change in the number of views will take place in one transaction with other requests

Answer 1

store views in redis, for example
It has atomic increment operations.
And in general, if mysql then do something like this
UPDATE table SET count = count + 1
