Best way to store the website logs?

Currently I am using a MySQL database to store every move done by my website users. For example:

• What the users type
• In which section are they
• etc

Every time the web is reloaded, this information is stored as a new row. All of this is done to be able to see the users breadcrumbs. Now, I have too many users therefore the table is getting huge. What could be the best way to store all this info and be able to query it?
