DBIx::Class::StorageDBUserCContributedgPerlBDocumentation::Balancer::Random(3)

NAME
       DBIx::Class::Storage::DBI::Replicated::Balancer::Random - A 'random'
       Balancer

SYNOPSIS
       This class is used internally by	DBIx::Class::Storage::DBI::Replicated.
       You shouldn't need to create instances of this class.

DESCRIPTION
       Given a pool (DBIx::Class::Storage::DBI::Replicated::Pool) of
       replicated database's
       (DBIx::Class::Storage::DBI::Replicated::Replicant), defines a method by
       which query load	can be spread out across each replicant	in the pool.

ATTRIBUTES
       This class defines the following	attributes.

   master_read_weight
       A number	greater	than 0 that specifies what weight to give the master
       when choosing which backend to execute a	read query on. A value of 0,
       which is	the default, does no reads from	master,	while a	value of 1
       gives it	the same priority as any single	replicant.

       For example: if you have	2 replicants, and a "master_read_weight" of
       0.5, the	chance of reading from master will be "20%".

       You can set it to a value higher	than 1,	making master have higher
       weight than any single replicant, if for	example	you have a very
       powerful	master.

METHODS
       This class defines the following	methods.

   next_storage
       Returns an active replicant at random.  Please note that	due to the
       nature of the word 'random' this	means it's possible for	a particular
       active replicant	to be requested	several	times in a row.
