Time complexity:: O(N) where N is the total number of elements in all given sets.
ACL categories:: @write, @set, @slow,
Compatibility:: Redis Software and Redis Cloud compatibility

Note:

This command's behavior varies in clustered Redis environments. See the multi-key operations page for more information.

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.

Required arguments

destination

The key to store the resulting set in.

key [key ...]

One or more set keys. The difference is the members of the first set that are not present in any of the subsequent sets.
