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
its 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 replicants 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.
