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.
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.
@@TinyTechnicalTutorials 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
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. 😊
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. :)
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
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: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-ZGGpEwThhrM.html. But depending on the "state" details, there are some additional things you might need to do.
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
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!
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 again, Babak! The Solutions Architect Associate course is finally live! Hopefully worth the wait. Enjoy! :) zerotomastery.io/courses/aws-certified-solutions-architect-bootcamp
