this is only for MySQL .. right? but for other DB's how it will fail?
@AsliEngineering Күн бұрын
ID can exhaust on any database. The error will be different, but the writes would still fail.

Can we shard data on multiple parameters? I am assuming it would work like, in this case, input a user id and categiory(optional) and output the nodes in which data can be found. I don't sharding the data in this way is correct because this might introduce latency in data retrival. Also if you could create a video about types of sharding like application level sharding, database proxy sharding etc. That would be great!

Hi Arpit, Thankyou for such an amazing explanation. I wanted to ask you a question. Is it possible that our hash space gets skewed up at a certain point like the files are inserted on the left side of the hash space and the storage nodes are inserted on the right or vice versa? If yes, so wouldn't it result in the celebrity problem? I might be missing something here. Would love to hear your thoughts. Thankyou

If whats app has all of public keys imagine, When user 1 encrypt with private key and send to user 2. User 2 get messge by using public key user 1. This can be done by whats app to. How can prevent deciphering our data by whats app?
@strotpaliya 7 күн бұрын
Hi Arpit, First of all thanks for the awesome video. I am wondering how they are able to support Strong Consistency over GSI. They classify Get ongoing orders by passenger id query pattern as transactional but they are leveraging GSI to support this query pattern and GSI is eventually consistent and when we are talking about a high TPS system serving millions of transactions per day the error rate scenarios becomes very high in number.
@AsliEngineering 6 күн бұрын
It was okay for them if data was eventually consistent. Grab only needed strong consistency (if any) for this main PK which is orders and not while getting all orders for a pax. So, it was totally fine for them to relax the constraint here. Also practically, the replication lag in GSI is not too high. Assume a lag of 5 seconds (relatively high, AWS says it would be between 0.5 to 2.5 that too across geographies), still after the user has created an order, the user is very likely to remain on order page to live track it or minimize the app. How many of them would even go to the orders page to see all orders. Even if they do, it will take them atleast 2 second to tap that icon and reach the screen. Enough time gap for the updates to catch-up. So, even when GSIs are eventually consistent it is totally okay UX.
@strotpaliya 6 күн бұрын
@@AsliEngineering Yeah even that is what i was thinking that their use-case might not be of a strong consistency but their article got me confused where they mentioned otherwise. It makes sense if it is purely required from UX perspective.

Why do they use both kafka and SQS if both serve the same purpose, they could use SQS with a dead letter queue only
@AsliEngineering 6 күн бұрын
For Grab SQS is just a fallback option in case Kafka goes down. Given that it charges on demand you won't pay anything if Kafka never goes down. Also, SQS and Kafka don't serve the "exact" same purpose. SQS, or any msgs queue offer better elasticity than msg stream like Kafka. You can scale up and down consumers easily while concurrency in Kafka is limited by the number of partition.
