In the video series, I delved into JunoDB, a key value database, focusing on its high security measures crucial for platforms like PayPal. JunoDB boasts impressive performance metrics, achieving a P99 latency of 4 milliseconds with 45,000 requests per second. Security is paramount, with data encryption in transit and at rest, managed by a key management system. The video emphasizes the importance of selecting the right tools and architecture, showcasing JunoDB's design choices for security and performance in a financial platform context.

Fantastic! Loved the series.

Great Series.!!! Arpit gave a good jist of how much engineering goes behind in various context's. I have a question around what would be you approach to choose a techstack for a project ? (I feel any one approach cannot be called as a correct one in this context but still want to get a point of view from your side )

Hi Arpit, Really enjoying this series. Thank you 👍🏼 Few questions 1. Which layer does the client authentication happen in juno db? 2. I am not familiar with go lang and curious how it compares to Java for paypal to choose Go? 3. How does the kms work with juno db if used as in memory?

@Arpit could you please configure your channel to have ads either in the beginning or end of the video, in between ads end up breaking the link when watching your videos. Thanks for all the amazing content always look forward to your videos.

KZbin injects them. Have very limited control over it.

Really liked this GoodNotes template. This is not in Goodnotes default templates, right? Can you upload & share link if you don't mind?

At minute 10:23 you said that even if you have 10-15 cores and you use a single threaded application it will only make use of a single core. However, what if i have single thread on each core and handle the request to each thread using a balancer.

[@AsliEngineering]

then each thread will own its own isolated instance of data a mimicking a shared-nothing architecture. If you want all threads to share the data then they become a regular multi-threaded implementation requiring you to apply concurrency control primitives.
