Read All Rows From Selected Columns

[Neofield-Dylan]

Is there a way to read all rows from selected columns when creating cursor ?

I noticed that cursor has rowGroup which has all the data that I need to fetch, but I am not sure if always it will have all rows fetched or it's just because the data I loaded is small.
Because it will be much better to get all the rows in this way or than having to iterate with cursor.next

As far as I am aware there is not, but it would be a nice improvement, and potentially help with speed as well.

That's exactly why I want it.
Also, it's really bad design having to iterate with while loop checking if next() return null value to break the loop.
I ended changing to write .feather files and reading with apache-arrow.
With these changes, I just have two lines: one to create table passing the buffer and another to call .toArray function
And it's 2x faster than before. Clean code. Faster code. Just Perfect!
