Redis ZREM
Redis sorted sets store unique elements in an ordered manner. Hence, it can be used in low latency applications such as priority queues, real-time leaderboards, secondary indexing, etc. Each of these set elements is assigned a rank and placed in ascending order based on the score value. Several commands are available to add, update, and remove the sorted set members efficiently. The most important thing about sorted sets is that after the addition or removal of a set member, it still manages to maintain the member ranks and order.
