SYNOPSiS

    __PACKAGE__->config({
        traits => ['Replicated']
        connect_info => 
            ['dbi:mysql:master', 'user', 'pass'],
        replicants => [
            ['dbi:mysql:slave1', 'user', 'pass'],
            ['dbi:mysql:slave2', 'user', 'pass'],
            ['dbi:mysql:slave3', 'user', 'pass'],
        ],
        balancer_args => {
          master_read_weight => 0.3
        }
    });

DESCRIPTION

Sets your storage_type to DBIx::Class::Storage::DBI::Replicated and connects replicants provided in config. See that module for supported resultset attributes.

The default "balancer_type" in DBIx::Class::Storage::DBI::Replicated is ::Random.

Sets the "master_read_weight" in DBIx::Class::Storage::DBI::Replicated::Balancer::Random to 1 by default, meaning that you have the same chance of reading from master as you do from replicants. Set to 0 to turn off reads from master.

CONFIG PARAMETERS

replicants

Array of connect_info settings for every replicant.
