Welcome back sir. We crave for your videos as I often found, you've some skill to deliver complex topic, smoothly. Whatever u taught I weight it in pure gold, due to ur pleasing presentation, rich content & detail explaination. I'm your big fan.👍
Let's hope you're back for good because certainly I've missed you. The quality of information in your videos is much better than what others have been publishing. Welcome back!!!
It's so good to have you back. I have cleared a lots of Java concepts with the help of your YT channel. That inturn helped me in many interviews. Looking forward to a great learning series with you. 🙂
You are HC Verma for computer science concepts. Every word you speak and sentence in your presentation is so important. Knowledge you share in 20 mins equivalent to 2 hr course.I am so happy you are back.
Good to see you back after such a long time! We were missing you. Hope you don't go now and keep teaching us. Your multithreading videos were too good. Still I refer those videos before interview.
Hey Bro, Can u explain below. Your explanation and content is very easy to understand and helps 1. Design patterns with help of help example each in simple and clear explanation. Why to use? 2. Best Practises in java and spring 3. How to select db and nosql db for project? 4. Compare different cloud platforms and its limitations?
Bro. Where have you been man. Been waiting for your videos for last 2 years. Your videos on concurrency are king. I have learnt so much from those videos.
you have brilliantly covered 2 chapters of design data intensive [almost] that I read in 15 days in just 20 mins video ... great video ... please continue to teach us more ... do you have some paid courses as well/mentorship ?
17:45 what would be the right schema in this case? I have a very similar use case where data duplication is brings the risk of updating multiple entries and if writes to a few entries fail, the datastore would be in an inconsistent state. I am not even sure if it is possible to gracefully handle this scenario or if we can recover out of such inconsistency. I cant think of any other way than to have some normalisation here eg: taking image urls into a seperate table and then having references to the image entries partition key in the main tables. But this again goes in the opposite direction of nosql i.e normalisation instead of denormalisation. Also, here, I would have to perform some sort of a compound query at application level like query first table to get image ids and then query the image table. [P.S Have been following you since past few years, really appreciate your work and have learnt a lot from your videos. Thanks for sharing your knowledge!!] [P.P.S I am using DynamoDb and transactionalWrites in DDB are limited to 25 items per transaction api call. My use case is to do such duplicate attribute updates across the whole table which goes beyond 25 by a lot]
When I was learning Java, your concurrency playlist really helped me a lot. It is so good to have you back. We missed you.
i thought the same too
Thank you so much for the kind words! I hope to create such deep content in other areas as well, fingers crossed.
@@DefogTech please 🙏
The java concurrency playlist still helpful today, I watched the thread locking videos and its help me a lot and easy to understand.
Welcome back!!! So happy to see you and sharing production grade knowledge.
Bro, the quality of the content and explanation is unmatched, hats off like literally
Thank you so much 😀
I never visit any channel that I subscribed. But, you're the only channel that I visit every day to check for the update even though I subscribed.
Man your videos on concurrency solved my years of problem understanding java threads...
Missed you! I can never forget your Java concurrency series and your video about API gateway! I watched these before 3 years.
Welcome back!! Glad to see your content after a long time. Quality content like yours should be often

One of the most highest quality videos made on nosql. I do not understand why this has low views. Would probably discourage the content creator.

Can you talk about how to "create the correct schema" here at 17:44, how do you remedy or prevent situations like this in NoSQL land?
Yes, asked the same question above Mark. Cannot understand how to solve it.
