Returns members in a sorted set within a range of scores in reverse order.
ZREVRANGEBYSCORE
key
max min [WITHSCORES
]
[LIMIT
offset count]
Returns all the elements in the sorted set at key
with a
score between max
and min
(including elements
with score equal to max
or min
). In contrary
to the default ordering of sorted sets, for this command the elements
are considered to be ordered from high to low scores.
The elements having the same score are returned in reverse lexicographical order.
Apart from the reversed ordering, ZREVRANGEBYSCORE
is
similar to ZRANGEBYSCORE
.
O(log(N)+M) with N being the number of elements in the sorted set and M the number of elements being returned. If M is constant (e.g. always asking for the first 10 elements with LIMIT), you can consider it O(log(N)).
