DBIx::Class::Storage::DBI::Replicated::Replicant - A replicated DBI Storage Role


This class is used internally by DBIx::Class::Storage::DBI::Replicated.


Replicants are DBI Storages that follow a master DBI Storage. Typically this is accomplished via an external replication system. Please see the documents for DBIx::Class::Storage::DBI::Replicated for more details.
This class exists to define methods of a DBI Storage that only make sense when it's a classic 'slave' in a pool of slave databases which replicate from a given master database.


This class defines the following attributes.


This is a boolean which allows you to programmatically activate or deactivate a replicant from the pool. This way you can do stuff like disallow a replicant when it gets too far behind the master, if it stops replicating, etc.
This attribute DOES NOT reflect a replicant's internal status, i.e. if it is properly replicating from a master and has not fallen too many seconds behind a reliability threshold. For that, use "is_replicating" in DBIx::Class::Storage::DBI::Replicated and "lag_behind_master" in DBIx::Class::Storage::DBI::Replicated. Since the implementation of those functions database specific (and not all DBIC supported DBs support replication) you should refer your database-specific storage driver for more information.


Reference to the master Storage.


This class defines the following methods.


Override the debugobj method to redirect this method call back to the master.
