@@carstenberggreen7509 I appreciate the effort it takes to create videos and share knowledge, but I do agree he wastes too much time. He has this video on an "Advanced C#" playlist, but then spends 3 minutes creating a new project and keeps stopping throughout the video to spend a long time explaining basics of the language. For example, at 23:00 he spent 17 minutes to write 2 functions which are only a few lines of code each while talking about what an extension method is and what null is. Maybe I'm just the wrong target audience and it's more aimed at absolute beginners, but I do think if someone is at the point that they want to learn how to improve the performance of their app with caching, they're already very familiar with the language features he is using here.
Hey Tim, you’re an awesome teacher. I’ve been a huge fan of your videos because they are simple, focused on real world scenarios and inculcate best practices along the way. I would really like you to create a video tutorial on Kubernetes and docker. Really appreciate your services to the community, not a lot of people share best practices easily.
I showed off a lot on how to use Docker in this video: ua-cam.com/video/Yj69cWEG_Yo/v-deo.html I also have a Getting Started with Docker course: www.iamtimcorey.com/p/getting-started-with-docker I will be doing more with Docker and K8s in the near future.
Tim, this is the most instructive video I have found regarding using Redis for caching. I have looked at several, but they do not explain the level of details you have explained in this video. You have explained in a such way, that any beginner like me will understand and will be able to implement. Thank you, Thank you very much for doing this for us. I really appreciate it.
wozers! very easy to understand video on Redis. Before this i imagine to setup Redis is kinda complicated and to learning it takes time.. i was wrong! and very easy to use it in .NET Core project! thanks Tim!
I was just implementing Redis in my project and was struggling with an error I couldn't resolve. And boom, Tim Corey uploads a video on Redis. What are the chances!! Thank you
Thanks, Tim! Now we are really waiting for RabbitMQ! And waiting from you exactly because you can make it in the best way :) P.S. oh, just noticed a video about Azure service bus, it might be somewhat related, so I'm gonna watch it now!
PA I just love your series Tim, the tempo, the topics you cover, the quality of the samples.... and your invaluable real world insights. But I sometimes miss the UA-cam feature which divides your video in segments. If you add those timestamps, so medium, or even advanced developers (viewers with some experience with the reasons or scenarios) can skip a bit, It would be great. While preserving the ultra useful basics for the newcomers at the same time. That kind of organization in your course wound be even better. Certainly a win-win scenario. Thank you!
When you do see those on my videos, you can look at the video notes and see that they were usually provided by viewers like you. They are great but I just don't have the time to do it. If you are the type person that keeps notes and wants to place the timestamps/chapters in the comments, I will gladly add them to the videos.
Simple and easy to watch as usual. Brought me forward without having to read long tutorials. This was simple and elegant. Only struggle is that I have moved to VS2022 and .NET 6, so the Configuration/ConnectionString was a bit different, but simple once you know how.
Speed is the issue. Caching needs to be as quick as possible. Otherwise it isn't valuable. If you tried creating a caching table in SQL, for instance, every insert would trigger a log event in SQL. It would also write to the disk. That's at minimum. Then, when you did a lookup, it would create an execution plan, do a seek to the correct location, read that location off of disk, and then transfer the data. With Redis, everything is stored in memory. There is no writing to disk. There is no logging. This is a big difference.
hello master Tim, and thank you for all your great work I just got a job as a developer, a trainee currently, and your videos were very helpful to show my mentors that i am learning unfortunately, I am from Lebanon and I can pay anything online, but maybe when i start getting salary i will, and if i do i will register to your courses
The reason I do this work is so you can have a better life, not to force you to pay me money. I am thrilled to hear about your job. Check out my Dev Questions playlist/podcasts and my Blog to help you when you find workplace challenges. Both at IAmTimCorey.com. Good luck in your new position! I am very proud of you.
Excellent video @IAmTimCorey. Unlike your other videos, in the beginning of this video you did not tell us why use Redis and not IMemoryCache provided by Microsoft. Or in what situations to prefer one over the other!
Tim, one thing that might be useful (and I've done in the past) is a method for downgrading from Redis to local caching if it becomes unavailable (like when you unplugged the docker container). And then automatically switching to Redis when it does come back online.
Hi Tim, love the new video. I signed up to your C# courses and am really getting a lot out of them, so thanks for all you do. Suggestions for videos/courses. Something I'd really like to see is building upon some of the courses you've already done relating to databases. That is, accessing databases securely, I can see you have tutorials on accessing databases, but in a fairly recent video regarding database security you recommend users don't send credentials from their application to the remote DB for security reasons, you talked about using stored functions and creating our own API's to interact securely with remote DB, so perhaps a guiding showing us how to do this. For example a user sign in system from a WPF app to remote DB or getting product info from DB properly and securely. That would be really great to see, perhaps with Azure as well?
@@IAmTimCorey Lol yeah it was a bit longer than intended 😂 Edited it down, note to self, stop writing messages on multi sessions and forgetting what you wrote.
Yay a new practical video 🥰 Topic suggestion: Allocation free c#. What's span about? A lot of people getting in touch with C# through Unity so shaving of another 2ms from your render loop can actually matter! :)
Another question. What is the best way to handle it if the redis service is down and you cannot connect to it? Try-Catch in the LoadForecast() kind of solves it but it makes the application super slow if it is trying to connect to redis every time without success.
Great video Tim. I did have a question. Do you have any examples of setting up Redis to notify a .NET application/service whenever a key value gets changed? I've seen that Redis has that capability but haven't seen any .NET examples of how to subscribe to these event messages.
31:20 Why do we want the cached items for such a short time? Is this just general practice or a case-by-base basis? Great video and channel as well, thank you good sir!
It does depend on the situation. How quickly your data might change depends on the data. A list of US states won't change very often (but it may change, just to be clear). A list of customers changes quite a bit more quickly.
0:50 I'm learning C# MVC, and I'm struggling with where do I put my logic code, closer to MVC, using AJAX, that updates multiple elements - HTML DOM - independently and simultaneously. Simply told, how to update multiple elements of a (specific) HTML page using AJAX (async JS) requesting different types of data. With best regards, thank YOU.
Logic code in MVC should not live in MVC at all but in a class library (separate from the UI - remember, all of MVC is UI including the controllers). As for updating pages based upon Ajax calls, it sounds like you are basically just making API calls to MVC (or should be). Not sure what the issue with updating multiple elements is, though. That's on your JavaScript code to do. That is one of the reasons I prefer Blazor Server.
Tim... I was wondering why you dont access the redis cache from behind the service layer (ie inthis case the ForecastService ... which generally would either be a Data library or an API and thence would be more usable if we switched from razor to something else ?
This was a demo to show off how Redis works. It wasn't really designed to show it off in a real-world design. In the real-world, we wouldn't be getting data that is auto-generated. I put it where I did to show off what you would do at the end of the API, rather than mixing it with the data access and confusing people. I'll be using it in a start to finish course one of these days. Then I'll put it in the right place.
That is a bit specific. I have added this to Tim's list of possible future topics. He uses the list to see common trends and requests that would help the most folks.
You can. It depends on your need and what your setup looks like. Kubernetes is basically just a bunch of Docker containers. You put your entire stack in those sometimes. However, in other situations, it is better to have Redis on a dedicated server.
Great video! One tip on keeping it cleaner with your if/else with strings being null or empty (and the small bugs that can happen if you check for the wrong state) is to use the built in string method string.IsNullOrEmpty(stringVar)
Well, one of the basics is that an in-memory cache uses your memory. A database cache like Redis stores the data somewhere else. In-memory will be faster but it will also bog down your server if you use it with any scale.
Hello Tim. I noticed that the extension where the Set and Get exist is "static". Does this affect the way the data is accessed in an async environment? Will the threads wait for the using thread to exist?
Thanks a lot, Tim Corey. Please can you do a video on how to record tutorial videos for youtube? Do you record the video first before voice over or do you do both at the same time?
I can add that to the suggestion list. As for your specific question, I do everything together. I don't do voice overs. It is way too complicated and messy to try to do it that way.
Hi Tim, we can use Memurai, and AnotherRedisDesktopManager to manage memurai, its an alternative redis version for windows and more fast than redis. no need to run docker
The downside is that you need to install it. By running a Docker container, I don't need to install anything - when I need Redis, I just run one command. When I don't need it anymore, I run another command and it is gone.
I love it. I'm not sure what I would improve. It is amazing. It can connect to three different computers (which I use). The 10-key section is useful as well (for me), but if you don't need it, it would be fine without it.
Hi Tim, great short course to get started with Redis! While coding, I noticed you were getting an automatic prompt to bring in the namespaces of whichever classes you were using. It does not seem you were hitting Ctrl + . to import them. Please can you share what extension or option you are using to get that feature? Is it Resharper?
Hi Tim, thanks for your video. I have a question how can I tweak your extension file in case not to fail if redis server is down and continue to read the data from db?
Hi, I am getting this error when running command in the console: Connection Failure: If this issue persists, ensure your computer's firewall and proxy settings allow outbound TCP traffic to port 10225. Using the firewall feature on your cache may also block connections from the console if your IP address has not been allowed. How to overcome it?
Tim thanks for a fantastic video! I am trying to deploy this but hit a snag: I have a console app that connects to redis ; both are on docker containers using docker-compose. What should the connection string be from my console app to access the redis container?
@@IAmTimCorey thank you! Love your videos btw. They give me a great starting point into new topics that would otherwise feel too daunting to start with!
Thanks for another great video. I was just wondering, why do you put time variable in recordKey and set an expiration on the same record? Would it not be enough just to set the expiration and have the same recordKey every time?
Thanks for ur awesome & valuable video. I have one question. Imagine i have employee list of data into redis cache then i am creating a new employee. Now Can i set my new employee data into existing cache list data??
Thank you for the video! Could you do a video on Blazor WASM with Browser Cache? I am looking at doing a PWA and I wanted to understand the best practices for storing the data before going to the API (and failing gracefully when the API isn't available).
Fantastic video. There is a small bug on the LoadForecast, setting the key with "yyyyMMdd_hhmm" will not use 24 hours and mix 11h and 23h, should be "yyyyMMdd_HHmm"
Hey Tim, I am a basic C# self-taught programmer and I do my projects on VS. Some of the projects that ive created are making a pyramid of stars, calculating any year to know if it is a leap year or not, and reading the size of each folder I have in my C drive. With that, I do not have a degree yet, and would like to know if I have a chance of getting a job at a company as a junior developer or likewise. Thank you Tim.
I would suggest you need to build up some more breath. My Foundation series is the best place to start. If you have not already, check out this video - ua-cam.com/video/LUv20QxXjfw/v-deo.html It is intended to help you assess where you are and the topics you need to add to your base skills. I believe it will help you build on that base you have already. My goal is to make becoming a developer easier and I hope I can help you be successful through your full journey! Just don't give up. Its a journey of a life time.
Hi Tim, Another awesome video from you. I have a question for you. Like cookie authentication, do we have session based authentication in core? Redis could be more beneficial if we store the data for authentication purpose. I have seen various example of storing the data in session and retrieving back but nowhere found for authentication and authorisation purpose. Does session based authentication exists or it just used to store the data for state management?
Hi Tim, i have Problem with redis as Caching System. how to make it optinal when the Container is offline. if redis in Docker is off it should call Always the API which options should i add Thx
@@IAmTimCorey I did that, but it take around 10 second to show the 4 rows, even the rows are in privat list in c#, no DB or API calles. Any solution 😢 Thx
Tim I started a new job as a developer, worked mainly involved in object script programming IRIS , they are saying soon will switch to C#. I am beginner on C# , how quickly I can excel in my role and tell company know I’m more c# person .
I'm wondering that is Redis useful for cashing specific data belonging to each individual user? or there is better other option for this? I need to cache a large amount of data (about 10 MB per user) for searching in user data which is diff from others. The data that needs to be searched, dosen't need to interact with SQL server every time.
@@IAmTimCorey thx 🙏 so for development you encourage us to use docker. Can we use redis image which is hosted on docker to publish it on the internet? (I know my question seems kinda stupid, hope you understand my worries) i just read on redis document that "docker imagese of redis enterprise software are certified for development and testing only"...
Would you please a tutorial or course about C# Socket Programming (e.g Client - Server desktop application) ? Thank you in advance. I like your courses
Hi Tim, Thank you very much for Redis tutorial. Really learned a lot from this. But I just wanted to confirm if the same process needs to be done if i wanna to install Redis on Windows Server 2016.

I put it where I did to show off what you would do at the end of the API, rather than mixing it with the data access and confusing people. I'll be using it in a start to finish course one of these days. Then I'll put it in the right place.
@@IAmTimCorey Thanks for clearing that one up.... I suspected as much! How you get the time to do what you do is beyond me :-)
Thanks so much for your awesome content. You explain it so well, I am really impressed.
You're very welcome!
Thank you so much. Can you tell us about the interaction of Redis with GraphQL, in particular with the HotChocolate library?
That is a bit specific. I have added this to Tim's list of possible future topics. He uses the list to see common trends and requests that would help the most folks.
Can you please share your thoughts about N-Cache as we are using that? Should we switch to Redis are keep using that? Thanks for such nice content.
Added to my list to consider for future topics.
@@IAmTimCorey just waiting eagerly, bundle of thanks.
Tim have you thought about doing an into to AWS?
Added to the list, maybe someday I can get to it.
Hi Tim. Thanks for this video. Can you reply with a link to your Getting started with ASP.NET Core video you talked about in 1:47
Here you go: www.iamtimcorey.com/p/getting-started-with-aspnetcore
Thanks Tim, I loved the explanation!
Is it advisable to use redis in docker in production environment?
You can. It depends on your need and what your setup looks like. Kubernetes is basically just a bunch of Docker containers. You put your entire stack in those sometimes. However, in other situations, it is better to have Redis on a dedicated server.
@@IAmTimCorey thanks a lot for your answer!
Is there a way to make sure that when SetRecordAsync is executed, that record is added to another server and vice versa?
Great video! One tip on keeping it cleaner with your if/else with strings being null or empty (and the small bugs that can happen if you check for the wrong state) is to use the built in string method string.IsNullOrEmpty(stringVar)
Thanks for posting the tip
Q
Tim, would you, or would you not, recommend using Redis in production? Are there any "gotcha's" to be aware of if doing so?
I am a fan of it. Use it like I showed you and use it wisely and you should be fine.
Thanks a lot Tim!
Thanks for watching.
I'm still wondering what are the advantages of Redis Cache vs Dotnet core Cache in Memory ?
Could you please clarify when should I use one vs another.
Well, one of the basics is that an in-memory cache uses your memory. A database cache like Redis stores the data somewhere else. In-memory will be faster but it will also bog down your server if you use it with any scale.
Hello Tim. I noticed that the extension where the Set and Get exist is "static". Does this affect the way the data is accessed in an async environment? Will the threads wait for the using thread to exist?
Thanks a lot, Tim Corey. Please can you do a video on how to record tutorial videos for youtube? Do you record the video first before voice over or do you do both at the same time?
I can add that to the suggestion list. As for your specific question, I do everything together. I don't do voice overs. It is way too complicated and messy to try to do it that way.
@@IAmTimCorey Alright...Thanks a lot
Hi Tim, we can use Memurai, and AnotherRedisDesktopManager to manage memurai, its an alternative redis version for windows and more fast than redis. no need to run docker
The downside is that you need to install it. By running a Docker container, I don't need to install anything - when I need Redis, I just run one command. When I don't need it anymore, I run another command and it is gone.
Hi Tim, great video again. Out of curiosity, which keyboard model do you use? 😆
I use the Logitech MX Keys keyboard: amzn.to/3YYBwcy
@@IAmTimCorey Are you happy using it so far? Do you think it is rigid and not bumping back while typing? Also would you prefer TKL version?
I love it. I'm not sure what I would improve. It is amazing. It can connect to three different computers (which I use). The 10-key section is useful as well (for me), but if you don't need it, it would be fine without it.
Tim you're great!
Thanks
Hi Tim, great short course to get started with Redis!
While coding, I noticed you were getting an automatic prompt to bring in the namespaces of whichever classes you were using. It does not seem you were hitting Ctrl + . to import them.
Please can you share what extension or option you are using to get that feature? Is it Resharper?
That's part of the latest versions of Visual Studio 2019 (Community Edition).
@@IAmTimCorey Thank you Tim, i will check it out in the latest version. I currently have Visual Studio Community 2019
Version 16.7.7
Hi Tim, thanks for your video.
I have a question how can I tweak your extension file in case not to fail if redis server is down and continue to read the data from db?
Redis will timeout if it isn't available. Watch for that timeout and write the necessary code to ignore it and use the live data.
Excellent stuff
Thank you!
Hi, I am getting this error when running command in the console: Connection Failure: If this issue persists, ensure your computer's firewall and proxy settings allow outbound TCP traffic to port 10225. Using the firewall feature on your cache may also block connections from the console if your IP address has not been allowed.
How to overcome it?
Check the firewall. If you are using Redis in Docker locally, check to be sure you mapped the ports correctly.
Tim thanks for a fantastic video! I am trying to deploy this but hit a snag: I have a console app that connects to redis ; both are on docker containers using docker-compose. What should the connection string be from my console app to access the redis container?
You should have access to the container by name. You would use that name in the connection string.
@@IAmTimCorey thank you! Love your videos btw. They give me a great starting point into new topics that would otherwise feel too daunting to start with!
Thanks for another great video. I was just wondering, why do you put time variable in recordKey and set an expiration on the same record? Would it not be enough just to set the expiration and have the same recordKey every time?
Thanks for ur awesome & valuable video.
I have one question. Imagine i have employee list of data into redis cache then i am creating a new employee. Now Can i set my new employee data into existing cache list data??
You can invalidate the cache or add it to the cache.
Tim I really appreciate your video.
Would you be able to do a video on how to do searching with caching,
Thanks, I added it to the suggestion list.
Thank you for the video! Could you do a video on Blazor WASM with Browser Cache? I am looking at doing a PWA and I wanted to understand the best practices for storing the data before going to the API (and failing gracefully when the API isn't available).
Great suggestion! Added to the list.
Fantastic video. There is a small bug on the LoadForecast, setting the key with "yyyyMMdd_hhmm" will not use 24 hours and mix 11h and 23h, should be "yyyyMMdd_HHmm"
Thanks for sharing!
Hey Tim, I am a basic C# self-taught programmer and I do my projects on VS. Some of the projects that ive created are making a pyramid of stars, calculating any year to know if it is a leap year or not, and reading the size of each folder I have in my C drive. With that, I do not have a degree yet, and would like to know if I have a chance of getting a job at a company as a junior developer or likewise. Thank you Tim.
I would suggest you need to build up some more breath. My Foundation series is the best place to start. If you have not already, check out this video - ua-cam.com/video/LUv20QxXjfw/v-deo.html It is intended to help you assess where you are and the topics you need to add to your base skills. I believe it will help you build on that base you have already. My goal is to make becoming a developer easier and I hope I can help you be successful through your full journey! Just don't give up. Its a journey of a life time.
Hi Tim, Another awesome video from you. I have a question for you. Like cookie authentication, do we have session based authentication in core? Redis could be more beneficial if we store the data for authentication purpose. I have seen various example of storing the data in session and retrieving back but nowhere found for authentication and authorisation purpose. Does session based authentication exists or it just used to store the data for state management?
btw, how to set the specific cache for 15 mins?
Hi Tim,
i have Problem with redis as Caching System.
how to make it optinal when the Container is offline.
if redis in Docker is off it should call Always the API
which options should i add
Thx
Wrap the cache calls in a try catch and you should be good.
@@IAmTimCorey
I did that, but it take around 10 second to show the 4 rows, even the rows are in privat list in c#, no DB or API calles.
Any solution 😢
Thx
Tim I started a new job as a developer, worked mainly involved in object script programming IRIS , they are saying soon will switch to C#. I am beginner on C# , how quickly I can excel in my role and tell company know I’m more c# person .
The C# Mastercourse is the fastest and best way to become great at C#: www.iamtimcorey.com/p/c-mastercourse
thank you Tim. i just yet implement it in my site
You are welcome.
Great channel!
Thank you!
I'm wondering that is Redis useful for cashing specific data belonging to each individual user? or there is better other option for this? I need to cache a large amount of data (about 10 MB per user) for searching in user data which is diff from others. The data that needs to be searched, dosen't need to interact with SQL server every time.
Sure, that would work.
@@IAmTimCorey thx 🙏 so for development you encourage us to use docker. Can we use redis image which is hosted on docker to publish it on the internet? (I know my question seems kinda stupid, hope you understand my worries) i just read on redis document that "docker imagese of redis enterprise software are certified for development and testing only"...
On Blazor Wasm you can use the browser local storage for caching.
Yep. You might want to use Session Storage, though, since that won't clog up a user's machine between uses.
Would you please a tutorial or course about C# Socket Programming (e.g Client - Server desktop application) ? Thank you in advance. I like your courses
Thanks, I will add this suggestion to my list.
I am looking for MS Orleans with Tim Corey. If you can provide some help on that.
That's probably too deep for what I cover. I've got a lot of territory to cover before I get there. Sorry.
Hi Tim, Thank you very much for Redis tutorial. Really learned a lot from this. But I just wanted to confirm if the same process needs to be done if i wanna to install Redis on Windows Server 2016.
You should be able to use Docker there as well, although you can directly install Redis if you want.
