What is the best way to make your own metric (tracker)?

Question

Web traffic analysis

The client comes to the site, you need to fix where he came from, ip and so on.
What is the best way to do this according to loads, write to files in storage or directly to the database query?

Thanks in advance for your reply.

Answer 1

directly to the database
only update do not do
a good tone - write to memory and then insert in batches into clickhouse
