Not all index scans are equal is an article by Datadog, where they describe the idea of targeted DB indices and when to use those.

There is also some praise for their database monitoring tooling, but this is a vendor article after all.

The only thing is that they didn't mention that too many indices also comes with a price: you need to store and update them. So, always evaluate the performance for some period of time after adding indices.
