  18:00 one doubt here, as fixed window counter may face double amount of requests for short period in case of bursts, that server may not able to handle it should be false right?

  Hi, really like your content. The only question I have is that in the cache, does user_id refers to the id of the person who made the tweet? Tell me if I'm getting this right: Whenever a user wants retrieve newsfeed we get ids of all the users that this particular user follows from graph database, then use those ids to pull out the tweet_ids that corresponds to those user_ids (so that we only pull tweets were made by the users that this user is following) from the newsfeed cache, then pull out user info from user cache and finally use tweets_id to pull out tweets data from tweets cache. Is this how it works? Would really appreciate your reply! I'm really confused about the mapping between tweet_id and user_id, does the user_id refers to the id of the user who made the tweet?

  01:52 are you referring to the size of the table > 200 GB or was it the response time 200ms, because if it was size then its contradictory to your statement on size of postgres table with 8KB block size can't be crossing 32GB in size.

  Sorry, this design is not best practice. You have 3 to 5 seconds to process a payment request and if that response is not delivered it is reversed, you don't use idempotency or retries to try to get an approval, if it was not approved in the initial attempt time window it is dead. Maybe this design works for b2b payments where you control the clients attempts, but it does work when you are servicing a live customer waiting. But your design would work for things like account creation or something else, just mot money movement when a live customer is involved.
