Given a quiescent set, the cursor will produce identical results indefinitely. The cursor isn't ephemeral, it is a durable direct index into the set. As changes are made to the social graph, the result set will reflect the change, especially on the end as older entries are exposed to keep the set size constant, but will otherwise be stable.
Note that if you are repeatedly indexing into the same location in a set that had high insertion velocity at some point in the distant past, you just might see oscillation between a small number of nearly identical result sets due to a timestamp skew bug that was fixed long ago. -John Kalucki http://twitter.com/jkalucki On Mon, Jul 26, 2010 at 7:32 AM, soung3 <sou...@gmail.com> wrote: > > I'm interested in learning about how long cursor IDs are valid for in > the friends/ids and followers/ids methods.
