ZREMRANGEBYRANK key start stop

Time complexity: O(log(N)+M) with N being the number of elements in the sorted set and M the number of elements removed by the operation.

ACL categories: @write, @sortedset, @slow

Removes all elements in the sorted set stored at key with rank between start and stop. Both start and stop are 0 -based indexes with 0 being the element with the lowest score. These indexes can be negative numbers, where they indicate offsets starting at the element with the highest score. For example: -1 is the element with the highest score, -2 the element with the second highest score and so forth.


Integer reply: the number of elements removed.
