# Gitlab::EventStore is a simple pub-sub mechanism that lets you publish
# domain events and use Sidekiq workers as event handlers.
#
# It can be used to decouple domains from different bounded contexts
# by publishing domain events and let any interested parties subscribe
# to them.
#

# Define all event subscriptions using:
#
# store.subscribe(DomainA::SomeWorker, to: DomainB::SomeEvent)
#
# It is possible to subscribe to a subset of events matching a condition:
#
# store.subscribe(DomainA::SomeWorker, to: DomainB::SomeEvent), if: ->(event) { event.data == :some_value }
