You are soon to become everyone's go-to system design mentor...keep up the good work

great explanation, even better than paid system design resources.

No one can draw and explain these in 45 minutes, while also constantly being interrupted by the interviewer's questions. Through these videos you are putting wrong expectations in interviewers head :)

Thanks, Sandeep, for the great content. I cleared a FAANG interview by watching your videos for the role of Sr. TPM. Cheers!!

He has disappeared from the scene. codeKarle is easily the best ever with crystal clear explanation and with very strong fundamentals. Undoubtedly is the best!

Great material man. I have worked for 11 years at Groupon where we basically used very single of the technologies you are describing. All the information you share is GOLD for new and experienced engineer.s Keep it up. I have seen 2 of your videos so far and I'm already convinced that this is one of the best channels out there.

Thanks for the great content! Love the way you explain concepts in great detail and have a consistent approach across all designs. Some ideas for future videos that we are looking forward to -
1. Designing google drive
2. Designing logging and alerting system
3. Designing deployment service
4. Designing shared docs like google docs.

This is the best end-to-end flow I have seen for twitter system design.
It would be great if you can have separate videos for scaling and load balancing redis, kafka, Cassandra and point to those like you did for urlsortener, asset service, etc !!

Overall, thanks a lot :)

13:00 why is graph service not using neo4j etc i.e. noSQL graph db instead is simply using relational mysql ?

@codeKarle This content is easy to understand but it goes into great depth and talks about shortcomings and ways to address them to maintain scale/distributed nature. I am amazed at how easily the content is presented. It's very high quality indeed. Please put out more content!. One suggestion if I may mention - please spend couple of minutes for scale (network requests per min/hr/day/month, DB storage needed per week/month/year, Redis size considerations) as well a very hight level DB schema design at least for important tables. This will help us a ton. Kudos to your efforts!

Everytime before a tech interview I look for your videos and since you're not uploading a lot recently, youtube makes it really hard to dig those out. This tells me something about the work life balance you have right now, lol.
