ruby-sidekiq - 7.3.2+dfsg-1 main

Sidekiq uses threads to handle many jobs at the same time in the
same process. It does not require Rails but will integrate tightly with
Rails 3/4 to make background processing dead simple.
.
Sidekiq is compatible with Resque. It uses the exact same
message format as Resque so it can integrate into an existing Resque
processing farm.
.
You can have Sidekiq and Resque run side-by-side at the same time and
use the Resque client to enqueue jobs in Redis to be processed by Sidekiq.
