ZSCAN key cursor [MATCH pattern] [COUNT count] [NOSCORES]

See SCAN for ZSCAN documentation.

valkey-protocol(7) Array reply: a two-element array.

• The first element is a valkey-protocol(7) Bulk string reply that represents an unsigned 64-bit number, the cursor.
• The second element is an valkey-protocol(7) Array reply of member/score pairs that were scanned. When NOSCORES option is on, a list of members from the sorted set.

O(1) for every call. O(N) for a complete iteration, including enough command calls for the cursor to return back to 0. N is the number of elements inside the collection.
