Pagination involves providing a limited subset of the results of a database query. This is usually done for display purposes, but could easily apply to other situations. At first glance, it would seem the LimitIterator
class is ideally suited for the purposes of pagination. In cases where the potential result set could be massive; however, LimitIterator
is not such an ideal candidate, as you would need to supply the entire result set as an inner iterator, which would most likely exceed memory limitations. The second and third arguments to the LimitIterator
class constructor are offset and count. This suggests the pagination solution we will adopt, which is native to SQL: adding LIMIT
and OFFSET
clauses to a given SQL statement.
