Module: Tarantool::Model::Locking

Extended by:

ActiveSupport::Concern

Included in:

Tarantool::Model

Defined in:

tarantool-model/lib/tarantool/model/locking.rb

Overview

Optimistic locking on the attribute named by locking_column, when the model declares it. An update compares the stored version with the record's and bumps it, inside a transaction on storages that have them, so a concurrent commit on the same row surfaces as StaleObjectError instead of being overwritten.
