Hi Nana. Hope that youre Doing Great! Following youre Devops Classes. Along those videos, Can you please Help Us, How to crack the devops interveiw by answering the All the real time experince? Hope You understood.And Youre reply will make My day👍 😊 Thank You

This is not a Redis crash course - it's an ad for Redis. It does not teach you how to use Redis in the way that 90% of people use Redis (which is what I would expect a crash course in Redis to do).

[@dhavewala]

In September 2022, I was a zero on Docker and needed it with ECR to be able to deploy a test automation framework.. All tutorials except yours were useless.. it took me 15 hours but I deployed it!! From not having any background to doing it professionally.. Fast forward to today and you literally saved the day on the Redis front! Thank you 😊

[@muelladresse10]

Very interesting topic. I used Redis a short time ago in a project where multiple services needed to exchange data asynchronous and I have to say Redis solves this problem perfectly. The most amazing feature about Redis is its tremendous speed. By the way I appreciate the effort you take in creating your presentations. They always look really nice.

[@yangliu8353]

This is more than just about Redis. The scaling section is actually a good overview of how all databases scale. Love it.

[@PaxHominibusBonaeVoluntatis]

Hi Nana! I am very impressed the knowledge you are sharing on YT. This is so great! All pictures, graphs, animations, your voice and the knowledge itself! You are very hard working and knowledgeable person. I wish to myself to be like you are. Cheers!

Hi Nana, this was such a crazy good video for so many reasons! Thanks so much for making a video on Redis. You can really see how much time and effort went into this. - Just enough content to give you a complete introduction that’s not too long but doesn’t leave so many unanswered questions that you have to watch similar videos that might repeat 40% of the content - Question-answer style presentation where questions used are the ones you would have when beginning and in the middle of starting to use it - Attractive visuals which helps watchers more easily understand concepts but also implicitly keeps them engaged by helping them follow along the video better - Clear logical explanations that also use analogies and references people will likely understand to help bring new knowledge into existing knowledge

[@ecommercetechbuild1354]

Highly informative. I watched a couple more Redis tutorials on other youtube channels. Yet, this is by far the best one and is 10x times more knowledgeable and informative. Awesome work! Thanks a lot, Nana

[@AntiEevee]

Whats to expect if Reddis them selfs sponserd her

[@davidnewton4613]

Thank you for this great summary, I'm studying up for a system design interview and this was very helpful! It took me a moment to realize that you weren't saying "Many teams don't want to deal with this [F-word]" but "effort"! I was just nodding along, thinking yes, it's quite vexing, isn't it

[@karanhotwani5179]

Another awesome video. The reason I find it so impressive is because even though it is a Redis crash course, you didn't get into basic syntax and setting up Redis which I usually find in other videos and can be done easily with documentation. Instead you went into nitty gritty of things,important concepts and architecture side of Redis and once that is clear, using it is no biggie. Kudos. Keep up the work Nana. This video helped a lot. Thanks. ❤️

[@sudheer5379]

Putting something like this together is not an easy task, yet you nailed it with 100% accuracy! I really appreciate all you do!

[@adityanjsg99]

I learnt Docker, Kubernettees much needed for Mlops from Nana. Now learnt Redis for Data Ingestion in AWS. Her videos are knowledge dense, demand full attention and no fast forwarding!

[@reno3708]

After watching few of your videos, I was shocked when I realised your channel have 'just' around 390k subs. Very good content. Thanks !

[@AKA96369]

Wholly Smoke! is there anyone else who can explain a technology better than you? I don't think so! THANK YOU!!

[@GauravSharma-cg2iv]

The way of teaching is really appreciated. could you please share the practical lab so that we can understand in practical way as well

[@_ashout]

Usually love your videos but this one seemed a little biased. If Redis modules can essentially replace all the other technologies why haven't more companies adopted it? Surely, the specialized versions of the tools have some significant advantages. What are the drawbacks of trying to replace everything with Redis?

[@ambarishhazarnis9531]

Scale, redis is like a rdbms but in memory

[@jameskennedy674]

For huger databases I think this would present more of a challenge. This is why Redis is essentially used for caching services. However, it would appear based on the video that you could scale Redis out to multiple machines but I am not sure about its parallel processing abilities. Even Apache Spark which does its computations in memory still has some underlying storage system behind it.

[@nacs]

This was seriously just a sponsored video. Nothing objective, no listing pros and cons or anything. Terrible video from Nana.

[@TheEbbemonster]

Agreed, it is a bit like a sales pitch for the enterprises version. 1. Redis is easy 2. But it is really complicated 3. Buy our easy product

[@RahulKumar-zf4ps]

There are so many limitations of redis that's why u may not use as primary db : 1. u can't perform complex queries like sql 2. u can use CDN to improve user experience in different regions but u can't use CDN with redis

[@sakshigopaladas7026]

One of the best technical videos I have see. It is clear and informative. Thank you!

[@michaelvilain8457]

An excellent birds-eye view of all the features redis offers. I wondered about data persistence and you answered that quite throughly.

[@prakashgp4467]

Thanks, best video on Redis. Wish I had found earlier. Had watched many videos, most of them left many questions unanswered. Please cover these 1. How data is synced to replicas esp if in different region and latency 2. How cluster is managed, using zookeeper?

[@alvin_paul]

The best redis introduction i have listened to. It is very clearand straight to the point. Well done!

[@code8986]

I would love a video about Conflict-free Replicated Data Types with your clear teaching style. The "micro-introduction" to CRDTs in this video was worth the price of admission alone.

[@phamnhuthai6847]

I made an wms with redis cluster as primary database 😄 the result pretty good, but will need a lot of skill, research, try and retry till you found your fine-tune. We have several hundreads sku and 12 million S/N in our inventory. Can perform a search or pagination around 100ms on each request. Pretty good !

[@johnnosek731]

You are an excellent instructor. Thank you very much for producing this content!

[@-o-6100]

This is my first comprehensive instruction video on Redis and I genuinely have to say how concise, informative and easy to understand this video is as I understood 80-90% of the content without having to replay the video (this is rarely the case for me). I instantly subscribed to your channel just because of this

[@sjatkins]

Whoa. I thought you were nuts early on to say all these multiple specialized databases could be done in REDIS as I have done some interesting things with REDIS and am well aware of many things it can do. What I didn't know is about these specialized non-core modules. Thanks!

A very good journey around the topic if not familiar with the basic concepts. Thank you very much from Belarus

[@chouaibbayari1071]

Thank you for the concise and on point explanation of the inner workings and fledged features of redis . For aws ec2 you need to set delete on termination to false to preserve the ebs in case of termination or failure, and for better dr/bc u could or should make incremental snapchots to s3 which is a cheaper but more durable and highly available( 3 availability zones) storage solution, couple that with cross region replication and u`re good to go for disaster recovery. Thank u again and keep up the good work .

[@alibarznji2000]

This is awesome, I've been researching Redis for a week, and I'm looking forward to using it in my projects

[@Equilibrier]

Thanks Nana ! Maybe, if Redis will be a lead on the technical databases, in the future, RAM will get more cheap ;). I assume you can do all things (but Active-Active service) with Redis-standard (free tier) as well ? I mean, sharding and clustering but you don't have a special tool for configuring and monitoring that process, did I understood it right ?

Another brilliant video. You make it so much easier for architects to get solid, foundational overviews of important topics.

[@elimeleg]

Hi nana! You said in your video that the way redis works as a primary database, is that he has the redis core that allready supports storing different types of data, and than if you need you can expand it by using the different models that avaliable to you in redis. My question is: If the redis core is allready supports storing different types of data, whay do we need the extra models?

[@2441980ashutosh]

Thanks Nana , You have nailed it and the way you have presented the video is very valuable and beneficial for everyone .. Thanks a lot .

[@aliandy.jf.nababan]

Sharding and replicate SQL & NoSQL of so many microservices that are use various database hardly to do, especially when have to manage per CDN interdependensi server. You are really can make your audience get fundamental knowledge for administer server.

[@ragook3]

You mentioned that Redis can handle various types of data. However, when it comes to storing relational database data, there's a question about how Redis, which primarily operates as a key-value store, can effectively manage this type of data.

[@egamberdijabborov6586]

Thanks for sharing your knowledge with us! Your videos are very helpful for me.

[@1bigslug]

Thank you your endless knowlege never fails to impresss!!

[@limwsv]

Could you share a bit more about how Redis will handle disaster recovery if one of the nodes containing a shard goes down, example shard "C" at video timestamp 15.45? I am not clear how the data in shard "C" can be restored unless it is done from the snapshot or the file-appending. And if that's the way it is done, how is the data spread across A - H reconcile and consistency restored since there may be missing transactions in C not captured in the snapshot or append-file.

[@johnny555]

Each shard has its primary and replicas that it can recover data from.

Interesting concept to store everything on redis. But how you convert for example 2 sql tables, to redis. Let's simplify to strings only. You read/write it as json? How you handle situations, where you traditionally use realations?

[@1apocalyps]

This was what I needed. Well explained.
