I didn't upvote it, but I think the product does inspire discussion about why we don't have basic important features like mandatory "last accessed" metadata on external state sources. Think of the number of hours of pain due to someone being "sure" a database/api/resource wasn't used, and then removing it. I'm not really put off by the advert for that reason.

tracking access time (every read) is huge performance bottleneck. especially if reliably persisting this

same reason why filesystems are often mounted with noatime attribute !

[daenz]

Yes, the sensible default for this feature would be opt-out, like noatime, in case you need the performance boost and understand the implications of the choice.

This feature has zero performance impact on your database. It is powered by insights which is served from a separate data store.

I think they meant if you were to add this as a default metadata feature into mainline mysql
