get_range_slices getting deleted rows
Hi,
I'm trying a test scenario where I create 100 rows in a CF, then
use get_range_slices to get all the rows, and I get 100 rows, so far so good
then after the test I delete the rows using "remove" but without a column or
super column, this deletes the row, I can confirm that cos if I try to get
it with get_slice using the key I get nothing
but then if I do get_range_slice again, where the range goes between new
byte[0] and new byte[0] (therefore returning everything), I still get the
100 row keys
is that expected to be?
thanks
Nicolas Santini

No, checking the key will not do.
You will need to check if row.getColumnSlice().getColumns() is empty or not.
That's what I do and it works for me.

thanks,
so I need to check the returned slice for the key to verify that is a valid
row and not a deleted one?
