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,
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,)
that is stored
inside cassandra, how would it be possible to get list of row keys?
This list of row keys is going to be used to get a range of slices.
Thank you for your help.

What if i want 20 rows and the next 20 rows in a subsequent query? can this
only be achieved with OPP?

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.

yes but be aware that the keys will not in the right order.

Yes. But I don't think the retrieving keys in the right order was part of
the original question. :-)

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

Hi everyone,
Thank you to everyone that have responded to my email. I really
appreciate that. I am sorry for not making it clear in my original
post that what I am looking for is the list of keys in the database
assuming that the client application does not know the keys. From what
I understand,

Thanks Roshan,
I think I understand now. The setRowCount() is in the Java Cassandra
driver. I'll try to find the similar method in the Ruby API.
Kind regards,
Joshua
