This provides basic i/o stats api for key-value databases.

User can:

  1. Query overall stats. They persist during all database instance lifetime.
  2. Query intermediate stats since the last querying.

Would be great to have byte stats as well. Number of bytes written to the database before any amplification. I.e. combined key and value size.

Is there a way to get stats without clearing them? I'd expect stats to be accumulating over all of the run time.

I'll add another function for it

Hey guys, I decided to refactor a bit.

The main change is now overall statistics is always kept, so if user cares only about overall stats, he will always have it, no matter if any intermediate queries were performed.

Pls re-review @arkpar @dvdplm @ordian
