Log activities to help profiling / debugging

[armetiz]

As a Symfony developper, I want to develop a DataCollector to know more about our usage during development process.

A dedicated DataLoaderLogger with logged get and cached activities could be used to develop such a DataCollector.

• How many time keys have been fetched, with a ratio HIT / MISS.
• How many batches have been executed to fetch data

That look good to me, how can I help you to implement this?

I'm not an expert about the DataLoader internals / activities; So I can not implement the solution myself.

Maybe you could start with a simple implementation collecting only basic metrics?
