Class::DBI::Iterator - Iterate over Class::DBI search results

       Note that there is no provision for the data changing (or even being deleted) in the database inbetween
       performing the search and retrieving the next result.

perl v5.34.0                                       2022-03-28                          Class::DBI::Iterator(3pm)

       Any Class::DBI search (including a has_many method) which returns multiple objects can be made to return
       an iterator instead simply by executing the search in scalar context.

       Then, rather than having to fetch all the results at the same time, you can fetch them one at a time,
       potentially saving a considerable amount of processing time and memory.
