ZREMRANGEBYRANK key start stop
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.
