  Advisory locking for ActiveRecord

  

Advisory locking is a mechanism used to prevent concurrent execution of code without necessarily locking the database table or row. In core Ruby, this is implemented using mutex. In Rails, the Ruby gem with_advisory_lock can be used to add advisory locking (mutexes) to ActiveRecord when used with MySQL or PostgreSQL.

  Prevents duplicate Sidekiq jobs

If you use Sidekiq workers to make changes to your database, you can use SidekiqUniqueJobs to add unique constraints to Sidekiq queues. Uniqueness is achieved by acquiring locks for a hash of a queue name, a worker class, and a job's arguments. By default, only one lock for a given hash can be acquired. If an attempt to acquire a new lock is made, an exception SidekiqUniqueJobs::ScriptError is raised.
