Amazon/AWS DynamoDB Tutorial for Beginners | Create Your First DynamoDB Table and Items
ฝัง
- เผยแพร่เมื่อ 21 ก.ค. 2024
- AWS offers many purpose-built databases-meaning each “specializes” in certain types of use cases. DynamoDB is the primarily NoSQL offering, being used for high-traffic web applications, e-commerce and gaming. It’s highly scalable, performant, and offers a really flexible key-value schema.
In this hands-on tutorial, we’ll create our first DynamoDB table through the AWS Console, and then add two items, illustrating just how flexible the schema is. All in less than 5 minutes!

You can't believe how much I enjoy the calmness and simplicity of your videos. Thank you for providing us with those great and straightforward tutorials.
I don't know that anyone has called the videos calm before...I love it! 🥰 So glad they're helping. Thanks for supporting the channel!
@@TinyTechnicalTutorialsthe best on TH-cam!
These are exactly the kind of how-to videos I personally look for and enjoy the most. Quick, and to the point when I want a simple starter or rundown.
Thank you!
You bet! So glad it helped!! 😊🙏🌟
Your videos are so helpful. Your explanations are so clear. I love the Seinfeld references, too. 🙂 Thank you for your hard work.
Thanks so much, Matthew! And I like that someone got the Seinfeld references! 😁
Very well done! Especially nice that you showed the json array and nested object example. Also good demo of the ragged key-value-pair view of customers with different sets of key fields.
I'm so glad it helped! Thanks for watching! 😊
Learning from Brazil, easy and clearly your explanation right to the point!
Ola, Gilberto! :) Thanks so much for watching! Glad it was helpful.
That was excellent. Conveyed a lot of understanding in a short video - thanks so much - I'm now subscribed to check out more of your tuturials
Awesome, thank you! Welcome to the channel! 🙏🌟🤓

One small thing you do that I find is effortless but means so much is your use of context naming during your demos. Most people will create demos using naming like "bucket1", "function1","event1", "role1", etc, when it is 10 times more helpful to viewers to use "myTinyFlixFunction", "myTinyFlixRole". I've always done similar for my own presentations and really appreciate this effort in your demos. Good stuff
It's very clear way to understand how to create dynamodb. Thanks a lot 😊
Yay! I'm so glad it was helpful. Thanks for watching, and for the nice comment! 🙏🌟🤓
simple way of explaining... thx for the video
Absolutely! Thanks for watching! :)
Brilliant! Extremely helpful. Thank you.

Thank you SO much!!! 🤓🙏🌟
Thank you. You were spot on
Thank YOU! And I love your name, Bro, Do you even Code? 😂👏
Seinfeld fan?
Thanks for the video - really useful bitesize info.
Ha! You're the first one to ask! :) One of the best shows ever, in my humble opinion. Thanks for watching!
great video !
Thanks so much!! :)
wow, you are an AWS Ninja!
Thanks so much! Welcome to the channel! 😊
Quick question..
In relation DBs we do colulmes created_at / updated_at.
Do you do that in dinamoDB or nosql ?
Hey ReivenIV! 👋 Great question! DynamoDB doesn't automatically manage "created at" or "updated at" timestamps for items in the way that some relational databases do. You can manually add/update those attributes, though...just takes a little more manual effort. 😊
Hello, Im doing a university project where I should run a whiteboard application on atleast two seperate machines within my vpc, each application serving different set of users and I have to demonstrate that the distributed application running in my vpc is consistent in a way that all users will see the same state across different instances. can you help me how can I achieve consistency so that everyonce can see the same state ?
any tips for this project?
Hey Complete Study! Sounds like a fun project! :)
Can you clarify a bit more about users seeing the "same state"? Do you mean they see the same UI? Or are you talking about session state (for example, storing variables across pages, or adding products to a shopping cart)? The first thing that comes to mind is to set up a load balancer with an auto-scaling group. The auto-scaling group would use a target group that includes your two instances, and then the load balancer would distribute traffic across both instances. I've actually got a video for that: th-cam.com/video/ZGGpEwThhrM/w-d-xo.html.
But depending on the "state" details, there are some additional things you might need to do.
I was thinking of doing a basic Database project using RDS but I wonder if this might not be a better way to do it..? I assume you can batch input data from a CSV file to DynamoDB? And read it with Quicksight?
If I was making a really simple app from scratch - thinking something like having buttons indicating a type of activity and another group of buttons indicating mood, and storing button presses with date and timestamps - is there any reason this would be better to do with RDS?
I'm tempted now to try with this instead... :)
Thanks again, I love these tutorials. I'm not certified and looking for hands on mini projects to get more familiar with the services. Your vids are really great for people like me!
Hi Hikosaemon! Thanks for watching...I'm so glad you're finding the videos helpful! 🙏😊
For a simple app like you're talking about, RDS or DynamoDB would technically work. DynamoDB is going to be lighter weight, easier to set up, and easier to change in the future if you need to (you don't have to update schemas and relationships and such). It will also be a lot more scalable and performant, if you plan to grow it in the future (though it sounds like you're starting small).
Yes, you can do batch ingest from a CSV file. Here's one way to do that: app.pluralsight.com/library/courses/developing-alexa-skills/table-of-contents
For QuickSight, here's a walk-through of how to do that (it uses Amazon Athena to query the data from DynamoDB first, then uses QuickSight to visualize it): dev.to/awscommunity-asean/visualising-your-amazon-dynamodb-data-with-amazon-quicksight-14n4.
Hope that helps! Definitely lots of options. :)
@@TinyTechnicalTutorials Wow, thank you!
I seen some Mongo DB projects, Can u make small video Extra benefits if any in this Dynamo DB compared to Mongo DB, i hope Mongo DB Atlas also similar cloud characteristic
Hi Narendra! I'll add this to my list for future videos. In the meantime, here's a comparison chart that might help? www.mongodb.com/compare/mongodb-dynamodb
Hi Amber, do you have any plans to make a course for AWS SAA? I took your cloud practitioner course and just passed the exam!
CONGRATS, Babak!!! This is wonderful news! :) I actually have an SAA course releasing hopefully in the next week with Zero to Mastery. I've made myself a reminder to loop back here with a link once it's published. Hang tight!
Hi Babak! Quick update on the Solutions Architect course. Things got delayed a bit over the holidays, but we're shooting for next week. Stay tuned! :)
Hi again, Babak! The Solutions Architect Associate course is finally live! Hopefully worth the wait. Enjoy! :) zerotomastery.io/courses/aws-certified-solutions-architect-bootcamp
Thanks
You bet! Thanks for watching! 🙏🤓🌟
ART VANDALAY!
LOL!! Yes!!! 😊
Can we apply queries to it
Yes! 🤓 You can query DynamoDB just like any other database. Here's the API documentation to get you started: docs.aws.amazon.com/amazondynamodb/latest/developerguide/Query.html
You have very nice voice
Awww, thanks so much!! 🤓🌟🙏
lol Seinfeld reference.
The best!! 😊
