Here’s what you’ll learn:
Why use AF|ART&HCOF as an abbreviation of the course name?
During our Apache Flink | A Real Time & Hands-On course on Flink course review, you might sometimes see us refer to it as AF|ART&HCOF for the following 2 reasons:
- We created the acronym by taking the first letter of every word (which was very ingenious and innovative, we know)
- We’re lazy and AF|ART&HCOF is simpler and easier for reviewing purposes
The full course name is 53 characters long, including blanks, while AF|ART&HCOF is 11 characters long.
You do the math.
Okay, we’ll do the math. We’re saving 42 characters every time we use AF|ART&HCOF.
So, just a heads up that we’ll be using this abbreviation sometimes, so you’re not left scratching your head and wondering what the heck we’re talking about whenever we refer to AF|ART&HCOF throughout the remainder of this review.
Is the Apache Flink | A Real Time & Hands-On course on Flink course for you?

The more you answer “yes” to each question, the more likely it is that you’ll like this course.
Can you understand what J Garg – Hadoop Real Time Learning’s course is about in 30 seconds or less?
Hopefully, you can easily grasp in 10 seconds or less what this online course is about simply by taking a look at the title that J Garg – Hadoop Real Time Learning chose for the course, “Apache Flink | A Real Time & Hands-On course on Flink”, as well as its subtitle: “A to Z, In-depth & HANDS-ON Practical course on a technology better than Spark for Stream processing i.e. Apache Flink”.
This combo of title and subtitle should be enough to communicate the purpose of the training if J Garg – Hadoop Real Time Learning is a good, clear communicator (which, of course, you want in a teacher).
In our opinion, if you still don’t know what AF|ART&HCOF is about after looking at these two things, then this is a red flag, and you might be better off not taking this class.

Apache Flink is the successor to Hadoop and Spark. It is the next generation Big data engine for Stream processing. If Hadoop is 2G, Spark is 3G then Apache Flink is the 4G in Big data stream processing frameworks. Actually Spark was not a true Stream processing framework, it was just a makeshift to do it but Apache Flink is a TRUE Streaming engine with added capacity to perform Batch, Graph, Table processing and also to run Machine Learning algorithms.

Are the AF|ART&HCOF lessons clear, specific, and organized well?
Part of the (good) problem with Udemy’s online courses, such as the Apache Flink | A Real Time & Hands-On course on Flink course, is that the instructors are constantly updating them, including adding and renaming lessons.
So it makes no sense whatsoever for us to list out all the modules and lessons in the AF|ART&HCOF course here, because you can just as easily go to the Udemy course page and get all the up to date course structure as of right now.
We do, however, have some tips about reviewing J Garg – Hadoop Real Time Learning’s course structure, so that you can get a better sense of whether this program is worth your time or not.
In a nutshell, you want to scan the the titles of the different sections and lessons of the course, and verify that they are clearly relevant to the course’s name, Apache Flink | A Real Time & Hands-On course on Flink, as well as the course’s subtitle, A to Z, In-depth & HANDS-ON Practical course on a technology better than Spark for Stream processing i.e. Apache Flink.
If the section names and lessons are clear, specific, and relevant, then it’s a good sign that AF|ART&HCOF is potentially a good, useful course for you, and you can have more confidence in J Garg – Hadoop Real Time Learning’s teaching abilities and lesson planning.
On the other hand, if the module names are confusing, vague, or irrelevant, then this is a red flag, which might indicate that the program is worth skipping.
Have you taken some free lessons from J Garg – Hadoop Real Time Learning that you enjoyed?
Have you already learned something from J Garg – Hadoop Real Time Learning that you valued or enjoyed?
For example, does the Apache Flink | A Real Time & Hands-On course on Flink training have some free lessons that you can try? (Almost all Udemy instructors will give you at least one or two lessons for free to help you make a better, more informed decision before enrolling in their course.)
But if you weren’t able to get any AF|ART&HCOF lessons for free, have you perhaps watched a YouTube video by J Garg – Hadoop Real Time Learning, or perhaps come across this instructor’s thoughts on Quora, Facebook, LinkedIn, Github, Reddit, or some other platform?
Or have you perhaps even taken one of J Garg – Hadoop Real Time Learning’s free courses or free webinars? (Many online teachers offer these freebies, which is a great way to get to know them and evaluate their teaching methods before buying one of their courses.)

Prior to August 21, 2025, there were 5,456 students enrolled, 646 reviews / ratings, and it was overall rated 4.4 out of 5.
Obviously, the more highly other students rate AF|ART&HCOF the better, but no matter what, keep an open mind when reading the reviews, since you might still like a course a great deal that other students dislike.
After all, everyone’s got their own opinion.
We recommend that you spend only a couple minutes scanning the AF|ART&HCOF reviews to get an overall sense of them. You don’t have to read each one!
Is J Garg – Hadoop Real Time Learning responsive to student questions in the AF|ART&HCOF training?
You can see what other students have to say about this in their AF|ART&HCOF reviews.
But, our simple all time favorite way of gauging an instructor’s responsiveness is to simply email the instructor and see if or how they respond.
In this case, Udemy has a messaging system for students / anyone who has an account, and you can send J Garg – Hadoop Real Time Learning a message through this system quite easily, even if you haven’t bought AF|ART&HCOF yet.
For example, you could say, “Hi, and I came across AF|ART&HCOF while looking at IT & Software courses on Udemy. If I enroll in your training, would you mind if I asked you any questions along the way?”
If you use this approach, the response (or lack of response) from the professor will tell you everything.
Obviously, the quicker the response the better!
Are you comfortable going through the lessons in Apache Flink | A Real Time & Hands-On course on Flink on your own, online?
This is a big one, because Apache Flink | A Real Time & Hands-On course on Flink is an online course as opposed to a course that you physically take in a classroom.

Yes, you will be able to interact with the students and the teacher, J Garg – Hadoop Real Time Learning, online, but it’s a different kind of experience than what you’d get if you were interacting with them in person.
This is not a big deal to most people, but it might be something for you to consider if you feel like you do better taking classes in person rather than learning online.

It will instantly give you the best coupon code we could find for J Garg – Hadoop Real Time Learning’s online training.

FYI, the methods below will help you not just with getting AF|ART&HCOF for a better price, but also with any other J Garg – Hadoop Real Time Learning Udemy course that you’d like to get for cheaper.
How can Google help you get a AF|ART&HCOF discount?
To use this method, do a Google search for the AF|ART&HCOF training, but in your search query, be sure to add words like coupon code, promo code, deal, sale, discount, and Udemy.
For example, you might do a search for “Udemy Apache Flink | A Real Time & Hands-On course on Flink promo code” or “Apache Flink | A Real Time & Hands-On course on Flink udemy coupon codes” and see what turns up.
Similarly, you can use the same combination of search terms with J Garg – Hadoop Real Time Learning’s name and see what happens.
For example, you might do a Google search for “J Garg – Hadoop Real Time Learning Udemy coupons” or “J Garg – Hadoop Real Time Learning course coupon codes” and see if that helps you.
However, in general, it’s far more powerful to do a search for deals and coupon codes with the actual training’s name, than with the instructor’s name.
So in this case, for example, prioritize searches for “Apache Flink | A Real Time & Hands-On course on Flink coupons” rather than “J Garg – Hadoop Real Time Learning coupons”.
How can a Udemy sale get you AF|ART&HCOF for cheaper?
Every once in while, Udemy will do a sitewide sale where they offer all (or almost all) their courses at a discounted price. For example, one of the best sales is where every course is only $10 or $9.99.
So, if you’re interested in saving as much money as possible, you could wait and see if you can get AF|ART&HCOF for this cheaper Udemy sale price one day.
The problem is that these sales only occur sporadically, so you might be waiting for a while. Also, if J Garg – Hadoop Real Time Learning decides not to participate in the site wide sale, then you won’t get a discount on AF|ART&HCOF, even though you could get a great discount on almost any other class at Udemy!
To understand this, think of there as being two different coupon categories for the AF|ART&HCOF course. Category one is an official Udemy coupon (which instructors can opt out of), while category two is a coupon offered directly by the instructor.
At the end of the day, it doesn’t matter what kind of a coupon tag you’re dealing with (for example, “officially from Udemy” or “officially from the instructor”), as long as long as as you’re dealing with active coupons that get you a better price.
How can you get a AF|ART&HCOF discount from J Garg – Hadoop Real Time Learning?
If you’re really serious about getting “Apache Flink | A Real Time & Hands-On course on Flink” for the cheapest price possible, then perhaps one of the most powerful things you can do is get a coupon code straight from J Garg – Hadoop Real Time Learning, instead of waiting for a Udemy sale.
To do this, you can use either the direct approach or an indirect approach to try to get your discount.
With the direct approach, the big idea is to simply get J Garg – Hadoop Real Time Learning’s contact info in some way or another (whether it’s email, or Twitter, or whatever else).
Then you send a message saying something like “I’m interested in enrolling in Apache Flink | A Real Time & Hands-On course on Flink. Do you happen to currently have an active coupon code for it that I could use?” (And then, hopefully, you’ll get a reply with your discount code.)
On the other hand, with the indirect approach, you join J Garg – Hadoop Real Time Learning’s mailing list, if you can find it, and then you hope that at some time AF|ART&HCOF will be promoted to you at a discount.
By far, the more powerful approach is the direct approach, because it tends to get results faster. But you can experiment with the indirect approach and see if it works for you.
Can you get AF|ART&HCOF for free?
Of course, the best possible price for the AF|ART&HCOF training is free! As in, you pay no money whatsoever.
And guess what? Sometimes Udemy instructors provide coupon codes that enable students to take their courses for free. So, perhaps it’s possible that J Garg – Hadoop Real Time Learning has done this.
Basically, if you’re trying to get this program for free, you will want to search for the course’s name along with other words like free coupon, or 100 off coupon.
For example, you might do a google search for “Apache Flink | A Real Time & Hands-On course on Flink free coupon” or “Apache Flink | A Real Time & Hands-On course on Flink 100 off coupon” and see what happens.
But keep this in mind: often, Udemy teachers will offer a free coupon for their course when it first opens to get some publicity and reviews. And then, after a few days, they’ll make the coupon expired.
So even J Garg – Hadoop Real Time Learning has offered free coupons for AF|ART&HCOF in the past, the odds are likely they will all be currently expired. This is a common pattern that we have found.
What about a AF|ART&HCOF free download?
It’s important to understand that there’s a difference between getting full access to the AF|ART&HCOF training for free legally with a free coupon code vs. finding a way to download AF|ART&HCOF illegally.
If you really want to go the download route, you can do a google search for something like “Apache Flink | A Real Time & Hands-On course on Flink download”.
And if that doesn’t get you the results you want, you can add the word “free” to your search.
For example, perhaps you could do a google search for “Apache Flink | A Real Time & Hands-On course on Flink free download”.
However, even if you get some results from these searches, we do not recommend that you take this course of action.
First of all, there are some shady sites out there that could be trying to infect your computer.
Second, J Garg – Hadoop Real Time Learning created this course and deserves monetary compensation for it.
And third, if you go the free download route, you’ll be missing out on a lot of value, because you won’t be able to ask the instructor questions or interact with the other 5,456 students enrolled in the program.
Can you get a refund on Apache Flink | A Real Time & Hands-On course on Flink if you don’t like it?
Let’s say that you used our tips above, and you were able to buy the AF|ART&HCOF training at a fantastic discounted price. So at this point, you’re super excited.
Then, you actually dive into J Garg – Hadoop Real Time Learning’s course, and you discover that it just isn’t for you for whatever reason.
And now you’re super bummed, because you feel like it wasn’t money well spent.
Well, guess what?
Udemy offers a rock solid 30 day money back guarantee on all their courses, so you can get a refund on AF|ART&HCOF no matter what. And this means there is absolutely no risk.
Indeed, even if you left a super negative, critical review on the AF|ART&HCOF training, and then asked for your money back, you’d get a refund. For better or worse, there’s nothing J Garg – Hadoop Real Time Learning could do about it, since it is simply Udemy policy.
To sum it up: yes, you can get a full refund, so at the end of the day, don’t worry about the possibility of purchasing AF|ART&HCOF and not liking it, since you can always get your money back.
