Hi monks,

I have an application which draws data from different providers, some of them DBIC-based, others file-based, etc. I have all of these data providers nicely wrapped in classes, with roles and collections.

Now I need to query, sort and page the provided data together to be able to display it in a sorted-paged-filtered grid to end user. I've looked at several modules in the CPAN but can't piece it together into a comprehensive solution.

Basically, I've looked at Data::Page, Data::Bulk, among others but apparently there isn't something that brings it all together.

For instance, in my program: 

# searching
for my $provider ( @providers ) {
    $data->add_results( $provider->search( query=>$query, sorting=>{ c
+ol1=>'asc' } ) );
}

# group sorting
$data->sort( sub{ return $_[0]->{column} cmp $_[1]->{column} );

# paging
my $rs = $data->list_paged( page=>1, rows=>10 );
while( my $row = $rs->next ) {
     ...
}

Of course, the data provided is humongous and I can't just load it into lists first for splicing.

Am I just nuts trying to do this?

Desperate for enlightenment here. Need a strategy or design pattern to focus on. Any comments are welcome!
