Help merchants to deal with over-populated SQL tables

[matks]

Is your feature request related to a problem?

A shop that has been running for years might accumulate a huge quantity of outdated datas: logs in ps_log table, emails of users who have not shopped for a long time, abandoned carts, cart rules with single usage that have been used a long time ago ...

All of these SQL rows will stay there and make SQL queries being run against the database slower.

Describe the solution you'd like

Ideally ? PrestaShop would be able to identify "useless data" and suppress them. For example "logs that are X months old" (and merchant/webmaster can configure X).

Alternatives you've considered

• a tutorial for merchants about how to identify and clean their old data
• a tutorial for developers about how to identify and clean their old data
• a warning system, able to monitor SQL tables size and properly warn developer/merchant about possible entanglement
