System design questions have become a standard part of the software engineering interview process. Performance in these interviews reflects upon your ability to work with complex systems and translates into the position and salary the interviewing company offers you. Most engineers struggle with the system design interview , partly because of their lack of experience in developing large-scale systems and partly because of the unstructured nature of SDIs. Even engineers whove some experience building such systems arent comfortable with these interviews, mainly due to the open-ended nature of design problems that dont have a standard answer. This course is a complete guide to master the SDIs.

It is created by hiring managers whove been working at Google, Facebook, Microsoft, and Amazon. Weve carefully chosen a set of questions that have not only been repeatedly asked at top companies, but also provide a thorough experience to handle any system design problem. Lets get started!

To keep things simple and efficient, GFS has a relaxed consistency model.

Metadata operations are atomic. They are handledexclusively by the master. Namespace locking guarantees atomicity andcorrectness, whereas the masters operation log defines a global total orderof these operations.

The Anatomy Of A Write Operation

The key point to note is that the data flow is different from the control flow.The data flows from the client to a ChunkServer and then from thatChunkServer to another ChunkServer, until all ChunkServers that storereplicas for that chunk have received the data. The control flow goes from the client to the primary ChunkServer for that

224 chunk. The primary then forwards the request to all the secondaries. Thisensures that the primary controls the order of writes even if it receivesmultiple concurrent write requests. All replicas will have data written in thesame sequence. Chunk version numbers are used to detect if any replica hasstale data which has not been updated because that ChunkServer was downduring some update.

Some Advantages Of This Course Are:

Covers dozens of popular designs.Includes a step-by-step explanation of basic, intermediate and advanced concepts.Includes more than 100 illustrations to complement the questions.One downside of the course is that Design challenges are arranged randomly and no specific ranking method is used.

Grokking the System Design Interview is a short, practical and concise course that has been divided into two sections. System design tools include 22 code snippets, 2 coding play areas, and more than 100 illustrations that help reinforce critical concepts.

In general, the course is good if your goal is to become familiar with the different types of systems design questions that are asked during the interview. So, I would say that the course is worth buying but it would have been better if the questions were updated according to the times.

If you feel that you need information not only regarding the questions that may or may not be asked during the interview, but also some real guidance from the mentors who are still working at FAANG and information about the course supplemented with different assignments, I suggest you opt for Advanced Problem Solving Using Systems Design course offered by Tutort Academy.

When you visit the website, an expert gives you a profile review and then connects directly with a mentor who will guide you through the course if it fits your requirements.

All the best and remember to do your own research by visiting the official websites too!

Parking Lot System Design Interview Question

This is a nice YouTube video explaining how to solve a popular parking lot System design interview question.

This video tutorial covers the following use cases

They also discuss APIs, Database models’ and database choice, how to make it distributed, and concurrency which is key system design concepts and often asked during coding interviews.

Here is the full video you can watch to learn how to solve this popular system design interview question.

A Encoding Actual Url

We can compute a unique hash of the given URL. The hash can then beencoded for displaying. This encoding could be base36 or base62 and ifwe add and . we can use base64 encoding. A reasonable question would be, what should be thelength of the short key? 6, 8 or 10 characters.

Using base64 encoding, a 6 letter long key would result in 64^6 = ~68 billion possible stringsUsing base64 encoding, an 8 letter long key would result in 64^8 = ~281 trillion possible strings

With 68 unique strings, lets assume six letter keys would suffice for our system.

If we use the MD5 algorithm as our hash function, itll produce a 128-bit hash value. After baseencoding, well get a string having more than 21 characters . Since we only have space for 8 characters per short key, how will we choose our keythen? We can take the first 6 letters for the key. This could result in key duplication though, uponwhich we can choose some other characters out of the encoding string or swap some characters.

What are different issues with our solution? We have the following couple of problems with ourencoding scheme:

KGS also has to make sure not to give the same key to multiple servers. For that, it must synchronize the data structure holding the keys before removing keys from it and giving them to aserver

6 * 68 = 412 GB.

A Few Years Ago A New Online Learning Platform Named Educativeio Wanted To Know If Id Like To Produce A Course For Them

Although I kindly declined , I was intrigued by the platform.

Why?

Well, for one, the course selection on Educative.io is not only robust but wonderfully specific.

For example, Reintroducing React: V16 and Beyond was created for web developers who dabbled in React a year or two ago, but need a modern refresher.

Ruby Concurrency for Senior Engineering Interviews? You dont get more specific than that.

Similarly, theGrokking the System Design Interview course on Educative.io is designed for those who need brushing up on a highly specific skill set: the system design process.

And it was created by hiring managers at Google, Facebook, Microsoft, and Amazon.

That means this course contains actual Google system design interview questions, for example.

Hdfs Consistency Model #

HDFS follows a strong consistency model. As stated above, each data blockwritten to HDFS is replicated to multiple nodes. To ensure strong consistency,a write is declared successful only when all replicas have been written

257 successfully. This way, all clients see the same view of thefile. Since HDFS does not allow multiple concurrent writers to write to anHDFS file, implementing strong consistency becomes a relatively easy task.

Why Do We Need Url Shortening

URL shortening is used to create shorter aliases for long URLs. We call these shortened aliases shortlinks. Users are redirected to the original URL when they hit these short links. Short links save a lot ofspace when displayed, printed, messaged, or tweeted. Additionally, users are less likely to mistypeshorter URLs.

For example, if we shorten this page through TinyURL:

educative/collection/page/5668639101419520/5649050225344512/916475904/

tinyurl/jlg8zpc

The shortened URL is nearly one-third the size of the actual URL.

URL shortening is used for optimizing links across devices, tracking individual links to analyzeaudience and campaign performance, and hiding affiliated original URLs.

If you havent used tinyurl before, please try creating a new shortened URL and spend some timegoing through the various options their service offers. This will help you a lot in understanding thischapter.
