📦 Redis Structure

• quiz:{quiz_id}:ques_ids – Set of question IDs for a quiz.
• upcomming_quiz_ids – Sorted Set where each quiz ID is scored by its end-of-day timestamp in IST.

Example:

from datetime import datetime, time, timedelta
from zoneinfo import ZoneInfo

ist = ZoneInfo("Asia/Kolkata")
end_of_day = datetime.combine(quiz.date_of_quiz, time(23, 59, 59), tzinfo=ist)

redis_client.sadd(f"quiz:{quiz_id}:ques_ids", *question_ids)
redis_client.zadd("upcomming_quiz_ids", {quiz.id: int(end_of_day.timestamp())})
