ZREVRANGE – Redis

Available since 1.2.0.

时间复杂度： O(log(N)+M) with N being the number of elements in the sorted set and M the number of elements returned.

Returns the specified range of elements in the sorted set stored at key. The elements are considered to be ordered from the highest to the lowest score. Descending lexicographical order is used for elements with equal score.

Apart from the reversed ordering, ZREVRANGE is similar to ZRANGE.

返回值

Array reply: list of elements in the specified range (optionally with their scores).
