NAME

Data::ObjectDriver::Driver::Multiplexer - Multiplex multiple partitioned drivers

SYNOPSIS

     package MappingTable;
 
     use Foo;
     use Bar;
 
     my $foo_driver = Foo->driver;
     my $bar_driver = Bar->driver;
 
     __PACKAGE__->install_properties({
         columns => [ qw( foo_id bar_id value ) ],
         primary_key => 'foo_id',
         driver => Data::ObjectDriver::Driver::Multiplexer->new(
             on_search => {
                 foo_id => $foo_driver,
                 bar_id => $bar_driver,
             },
             on_lookup => $foo_driver,
             drivers => [ $foo_driver, $bar_driver ],
         ),
     });
 
 

DESCRIPTION

Data::ObjectDriver::Driver::Multiplexer associates a set of drivers to a particular class. In practice, this means that all INSERTs and DELETEs are propagated to all associated drivers (for example, all associated databases or tables in a database), and that SELECTs are sent to the appropriate multiplexed driver, based on partitioning criteria.

Note that this driver has the following limitations currently:

1. It's very experimental.
2. It's very experimental.
3. IT'S VERY EXPERIMENTAL.
4. This documentation you're reading is incomplete. the api is likely to evolve
