Until Redis 4, all instrumentation happened in one gem: redis. Since Redis 5, instrumentation happens in a separate gem: redis-client. Because Redis 4 does not depend on redis-client, it’s possible for both gems to be installed at the same time. For example, if Sidekiq 7 and Redis 4 are installed: both redis and redis-client will be installed. If redis-client and redis > 5 are installed, than they will be in sync, and only redis-client will be installed.
