ZRANGESTORE

Introduction​

In Dragonfly, as well as in Redis and Valkey, the ZRANGESTORE command fetches elements in a specific range from a sorted set and stores the result.

Syntax​

ZRANGESTORE destination key min max [BYSCORE | BYLEX] [REV] [LIMIT offset count]
  • Time complexity: O(log(N)+M) with N being the number of elements in the sorted set and M the number of elements stored into the destination key.
  • ACL categories: @write, @sortedset, @slow

This command is like ZRANGE, but stores the result in the destination key.

Return Values​

  • Integer reply the number of elements in the resulting sorted set, stored in destination.

Code Examples​

dragonfly$> ZADD key 1 one 2 two 3 three 4 four
(integer) 4

dragonfly$> ZRANGESTORE dst key 1 3
(integer) 3

dragonfly$> ZRANGE dst 0 -1
1) "two"
2) "three"
3) "four"
