ZREMRANGEBYRANK

Available since 2.0.0.

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.

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.

Return value

Integer reply: the number of elements removed.
