| Summary : Tieable module for handling large arrays by paging
|
Description :
When processing a large volumes of data a program may run out of memory.
The operating system may impose a limit on the amount of memory a process
can consume or the machine may simply lack the required amount of memory.
Tie::PagedArray supports large arrays by implementing paging and avoids
running out of memory. The array is broken into pages and these pages are
pushed to disk barring the page that is in use. Performance depends on the
device chosen for persistence of pages.
This module uses Storable as its backend for serialization and
deserialization. So the elements of the paged array can be any value or
object. See documentation for Storable module to work with code refs.
When switching pages data from the currently active page is offloaded from
the memory onto the page file if the page is marked dirty. This is followed
by deserializing the page file of the page to which the switch is to be
made.
An active page is marked dirty by an *assignment* of a value to any element
in the page. To forcibly mark a page dirty assign an element in the page to
itself!
$large_array[2000] = $large_array[2000];
The defaults are \'page_size => 2000\', \'paging_dir => \".\"\'
