NAME¶

Catalyst::TraitFor::Model::DBIC::Schema::Replicated - Replicated storage support for Catalyst::Model::DBIC::Schema

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. The following can be set via "connect_info" in Catalyst::Model::DBIC::Schema, or as their own parameters. If set via separate parameters, they will override the settings in "connect_info".

pool_type¶

See "pool_type" in DBIx::Class::Storage::DBI::Replicated.

pool_args¶

See "pool_args" in DBIx::Class::Storage::DBI::Replicated.

balancer_type¶

See "balancer_type" in DBIx::Class::Storage::DBI::Replicated.

balancer_args¶

See "balancer_args" in DBIx::Class::Storage::DBI::Replicated.
