lib/gitlab/exclusive_lease.rb

+module Gitlab
+  # This class implements an 'exclusive lease'. We call it a 'lease'
+  # because it has a set expiry time. We call it 'exclusive' because only
+  # one caller may obtain a lease for a given key at a time. The
+  # implementation is intended to work across GitLab processes and across
+  # servers. It is a 'cheap' alternative to using SQL queries and updates:
+  # you do not need to change the SQL schema to start using
+  # ExclusiveLease.
+  #
+  # It is important to choose the timeout wisely. If the timeout is very
+  # high (1 hour) then the throughput of your operation gets very low (at
+  # most once an hour). If the timeout is lower than how long your
+  # operation may take then you cannot count on exclusivity. For example,
+  # if the timeout is 10 seconds and you do an operation which may take 20
+  # seconds then two overlapping operations may hold a lease for the same
+  # key at the same time.
