SINTER

SINTER key [key ...]

Available since:

Redis Open Source 1.0.0

Time complexity:

O(N*M) worst case where N is the cardinality of the smallest set and M is the number of sets.

ACL categories:

@read, @set, @slow,

Compatibility:

Redis Enterprise and Redis Cloud compatibility

Returns the members of the set resulting from the intersection of all the given sets.

For example:

key1 = {a,b,c,d}
key2 = {c}
key3 = {a,c,e}
SINTER key1 key2 key3 = {c}

Keys that do not exist are considered to be empty sets. With one of the keys being an empty set, the resulting set is also empty (since set intersection with an empty set always results in an empty set).
