‫Hey, what is going on, guys?
‫It is really absolutely amazing how this course became so popular and you guys love it.
‫Absolutely love it.
‫Thank you so much for the great ratings.
‫I appreciate every single one of you.
‫And so I decided to invest more into adding more content to this scores and reorganize the sections.
‫And I would just want to go through some of the stuff that I have been adding every month.
‫I have to add a few more content.
‫And really, really, it's been it's been an amazing experience.
‫You guys ask fantastic questions, which essentially lead to more content to the course and then the
‫course is growing.
‫I would say it's at 14 hours right now.
‫Obviously, you cannot finish it in one sitting.
‫You have to take it slowly digested and read through, get ideas, ask questions which which will lead
‫to discussions.
‫It's it's beautiful.
‫Really beautiful.
‫Let's go let's go through the stuff that I recently added.
‫Here's the course content I created.
‫The first section is basically all the courses, updates, last update I made, just physically updating
‫you guys making a video, what it was October 23.
‫But every month after that, I kept adding more content without explicitly making videos of all of them,
‫essentially tweet about it and and talk about in my YouTube channel.
‫But essentially that I'm going to add a new video here, too.
‫This is for April twenty twenty one acid.
‫I created this specific section for all the acid videos, you know, just because this is a very interesting
‫topic.
‫The idea of having atomistic on sustenance, isolation, enteropathy, I believe every engineer should
‫understand this.
‫So that's why I started adding more content to this examples and even more stuff coming in and fits
‫into this section.
‫So I believe it deserves its own s.m database indexing.
‫Man My God, I've been adding more and more content to this and exclusive content.
‫And I have videos coming here with Postcrisis Explain and so much other stuff as well.
‫So database indexing definitely keep a watch for this.
‫I'll keep adding more content.
‫And you guys have been asking me to make more content on the database indexing space.
‫So it's really, really huge partitioning.
‫Obviously another underrated feature of the DMS we don't talk about.
‫What do we talk about sharding.
‫A lot of partying is as important, as powerful of a concept.
‫I've been adding content to that database sharding.
‫Obviously, this is the main more mainstream and buzzword that we hear over there.
‫So I try to demystify it.
‫Whatever you get to learn here, as essentially I don't use tools or anything like that.
‫I try to build it from scratch.
‫So you have full understanding of what sharding really means.
‫And that's that's basically the key here.
‫Concurrency control locks, the idea of deadlocks, two phase locking, how to transactions are concurrently
‫trying to execute things, isolation that comes of isolation, database replication.
‫Another also underrated feature where you have a kind of a master primary database and you have other
‫replicas that can take these reads.
‫Right.
‫Then you can hit them directly.
‫Very, very powerful concept for horizontal scalability.
‫A lot of people say, hey, you know, that it was doesn't scale.
‫That is absolutely wrong.
‫You can scale them right.
‫You can do all these kind of things before jumping to other database systems.
‫You got to solve.
‫You have you have a lot of tools to solve your problem.
‫You don't have to move to another database.
‫Obviously, I am planning to make videos for Schoolcraft databases.
‫I don't think it fits into this course is probably going to be another court, but I want to give the
‫relational databases.
‫It's essentially it's justice because it's not given this justice.
‫A lot of videos from YouTube, I think free available here, ad free for you, like a system designed
‫that I've been doing on my YouTube channel.
‫This is available for you here to watch Ad Free.
‫Obviously, I've been I went through a software system designed a short URL system design.
‫It's all available here, Blanning to make more exclusive content for the course right here and introduce
‫the database engines to be three engines, three engines.
‫I know guys you asked me to make specific videos for these are upcoming, so watch out for that.
‫But essentially the engines, the database engines are so powerful.
‫This is the underlining cogs that.
‫Executes anything that above the database.
‫It's very, very critical to understand this and you will appreciate what the Dabis does when you actually
‫do this, obviously go through a demo that was Courcelles, another underwriting feature.
‫We don't talk about this stuff.
‫Stateful versus stateless cursors, client server side, curser versus server side.
‫So what is the benefit of both?
‫Why should I use this over the other?
‫I give examples of Python here.
‫Database security, again, another very powerful feature like what does it mean for the database to
‫be secure?
‫Really, what does it mean?
‫So we try to demystify some of the stuff here.
‫This is a you will not find any anything about this anywhere.
‫This is technically really exclusive home, morphic encryption.
‫This is a very fresh concept that let's go through the problem first.
‫The problem is when you store data on two database, it's also most of the plaintext.
‫You don't you never store encrypted data right.
‫In your besides password.
‫I'm talking right like a profiler who is a customer that is all plaintext and decrypt it.
‫Right.
‫So that means if your data is leaked, everybody got all the information on encryption, allows you
‫to store the data is encrypted and don't even have the key.
‫Let the key belong to the user.
‫So you don't really stick to the key because that's just pointless.
‫Right.
‫If you store the key in the database is just as Beutler's database Merfolk encryption is that is technologies
‫are being researched now to allow you to perform database searches or operations on encrypted data without
‫actually looking.
‫It's mind boggling.
‫Take a look at this.
‫This is beautiful stuff.
‫I use it and there's examples and stuff like that.
‫So it's at its infancy now.
‫And there's obviously various there's been discussions.
‫I try to pull whatever useful stuff here decide between Bosco's MySQL distributed transactions and discussions.
‫That is like if you willing to go florham beyond and we have a discussion right here, we can have these
‫discussions like how do you how does DASK what kind of protocols becomes really beneficial?
‫If I store, if I use in my database and all of stuff?
‫Guys, keep up the good work.
‫Thank you so much.
‫Appreciate you.
‫Thank you for the support.
‫Thank you for checking out the scores and make sure to read the course if you like it.
‫And I'm going to see you on the next one, you guys.
‫The awesome goodbye.
