OK, got it.
Tks for the explanation,

Stable order mean the keys will return in some kind of ordering (not alphanumeric, not numeric,), just in certain order.

For example, if you use setKeys("","") as first batch call and you got following result.

keyabc
key456
keydsg
key8jkg
keyag87
key45s
...

Then if you call with setKeys("keydsg","") again, you will get following result.

keydsg
key8jkg
keyag87
key45s
...

Hi,

I'm also facing the need to retrieve all row keys.

What do you mean with "stable" order?
From this thread, I understand paging method with RandomPartitioner will return all keys (shuffled, but missing key, no double key).
This seems to have already told, but I prefer to double-check...

Tks,

They are, however, in *stable* order, which is important.

Actually, if you want to get ALL keys, I believe you can still use
RangeSliceQuery with RP.
Just use setKeys("","") as first batch call.
Then use the last key from previous batch as startKey for next batch.
Beware that since startKey is inclusive, so you'd need to ignore first key
from now on.
Keep going until you finish all batches.  You will know you'd need to stop
when setKeys(key_xyz,"") return you only one key.
This is what I meant to suggest when I earlier said "So, if you want all,
you will need to keep paging forward and collecting the keys." :-)
