We can retrieve leveldb stats more directly?

[hadv]

Why we don't get the db stats directly from the Total line in the current leveldb output below?

Compactions
 Level |   Tables   |    Size(MB)   |    Time(sec)  |    Read(MB)   |   Write(MB)
-------+------------+---------------+---------------+---------------+---------------
   0   |          1 |      13.08174 |       0.00000 |       0.00000 |       0.00000
   1   |         62 |      96.60306 |       0.00000 |       0.00000 |       0.00000
   2   |        543 |     998.45153 |       0.00000 |       0.00000 |       0.00000
   3   |       1676 |    3369.03049 |       0.00000 |       0.00000 |       0.00000
-------+------------+---------------+---------------+---------------+---------------
 Total |       2282 |    4477.16682 |       0.00000 |       0.00000 |       0.00000

Instead of accumulating the data from the lines like current code?

// This is how a LevelDB stats table looks like (currently):

I guess the total wasn't part of the output when we've implemented this, at least looking at the example output in the exact code you linked.

And something irrelevant, Leveldb now supports to report stats in a single structure. Instead of parsing the stats in string format, it can be definitely easier. I guess it could be a starter task anyway.

Though if we go with Pebble in the long term, might not be worth to poke working code.

yeah, I think we can do smth like this?

Since we've switched the default over to pebble, we're not going to further work on leveldb integration
