Return information

Array reply: a two-element array.

  • The first element is a Bulk string reply that represents an unsigned 64-bit number, the cursor.
  • The second element is an Array reply of field/value pairs that were scanned. When the NOVALUES flag (since Redis 7.4) is used, only the field names are returned.
