Data::ObjectDriver::Driver::Multiplexer(3pm) User Contributed Perl Documentation Data::ObjectDriver::Driver::Multiplexer(3pm) 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 perl v5.12.4 2011-08-29 Data::ObjectDriver::Driver::Multiplexer(3pm)
