Searching is not the same thing as a range iteration, normally if you want to search a Key/Value than you'll need to scan the entire dataset.

A range iteration allows you to scan a subset of the data, and as long as they didn't fundamentally change how LevelDB works, than they will still support ranges.

In this case, you lost the sorted keys advantage that BTree gives you.

My point is that this project leans more towards exact key -> value lookups and a BTree is an overkill here.

I guess it depends on your use case, most of the use cases I've seen have been time series using range iterations which is incredibly fast, but I understand your concern if you're only using it for random gets.
Probably providing the option to create a btree or hash map would be nice.
