I am currently doing a detailed study on how to optimize my
application to be scalable.

I have thoroughly studied the lectures delivered by the engineers at
google, and my opinion: fantastic

In this case, my question comes from the presentation

Buildding Scalable Web Applications with Google App Engine whose
rapporteur was Brett Slatkin

In it, in the section "Building a Blog: Paging ", using the attribute
index, get to paginate infinite elements, using the index as a guide
for the next entry

Now, suppose you delete an entity, the attribute index would not be
consecutive. taking into account that, any idea howto  implement
paging that supports not only next and previous, but also, goto "n"
page number.?

thanks in advance,

Abel
