Hi,

I am running into CubDB timeout and not sure where to improve:

CubDB.select(ref, [min_key: {:tests, 1}, max_key: {:tests, 5}, min_key_inclusive: true, max_key_inclusive: true]) |> Enum.count()
5

CubDB.select(ref, [min_key: {:tests, 1}, max_key: {:tests, 100000}, min_key_inclusive: true, max_key_inclusive: true]) |> Enum.count()
100000

CubDB.select(ref, [min_key: {:tests, 1}, max_key: {:tests, 1000000}, min_key_inclusive: true, max_key_inclusive: true]) |> Enum.count()
<timeout>

The element’s format is simple, just {:tests, <number>}. I put 10 millions elements from 1..10_000_000 for testing the query. Do I miss anything, or there is better way to run query on large elements for CubDB?

Thanks a lot!
