Method: Dynamoid::Persistence#update!

Defined in:
lib/dynamoid/persistence.rb

#update!(conditions = {}, &block) ⇒ Object

update!() will increment the lock_version if the table has the column, but will not check it. Thus, a concurrent save will never cause an update! to fail, but an update! may cause a concurrent save to fail.
