- Usage:
SDIFFSTORE destination key [ key ...]
- Complexity:
- O(N) where N is the total number of elements in all given sets.
- Since:
- 1.0.0
This command is equal to SDIFF, but instead of returning the resulting set, it
is stored in destination.
If destination already exists, it is overwritten.
Examples
SADD key1 "a"
SADD key1 "b"
SADD key1 "c"
SADD key2 "c"
SADD key2 "d"
SADD key2 "e"
SDIFFSTORE key key1 key2
SMEMBERS key
