I have been looking for a video that will explain dynamodb streams to me in preparation for an exam. This video is prolly the best! This is short but comprehensive
brilliant! thanks for this video i had an issue with dynamodb streams and had to understand the foundation of dynamodb streams feature and this video helped a lot.... i believe the community needs more videos/tutorials and really real code examples... please, give us more and we can always help as well (start using aws resources and connecting them is something new to me... i was just used to normal ec2, s3, blablabla)! cheers!
Thanks Rejaine! I'm constantly putting out new videos on all sorts of AWS topics - especially those concerned with hooking up resources across services. Thanks again!
@@BeABetterDev thank you!!! I also found a dynamodb developer guide which has everything.. it just impressive!!! and it has 1 chapter about dynamodb streams api and kinesis adapter.. i was really confusing about this kinesis client library if we have the dynamodb streams api, but now I believe i got it and it has awesome samples to practise! =))) thank you so much again!!! all your content are amazing!!!
AWS Simplified a walkthrough of a Java application that uses the Amazon Kinesis Client Library and the Amazon DynamoDB Streams Kinesis Adapter. An example of data replication, in which write activity from one table and applied to a second table, with both tables' contents staying in sync to another consumer... Hehe
I watched all the videos and this is best playlist on DynamoDb. I have an interview tommorow and they mentioned knowledge about DynamoDb in JD. I hope I crack it and btw keep up the good job.
I love how you simplify the content with your used case , you make it seem so cool ! Just a tiny bit of suggestion , it'd be great if you could speak a bit louder in the future videos. You are awesome , keep going !!
Thank you so much Zainaba for the kind words. This was one of my first videos so my audio quality should be much better in my more recent ones. Thanks again and stay safe! Daniel
@@BeABetterDev I am currently studying for my first AWS certification: SAA-C02. I wanted to point out that the great value of this particular video is how it illustrates the integration of several AWS services. Until I watched this I really didn't grasp the full potential of lambda event sourcing. This is a shortcoming of the course that I'm taking which really tends to dwell on individual services rather than their integration. Is my understanding that SQS and KDS more or less follow the template that you illustrated with Dynamodb streams.
At the 11:15 mark - you mention that "it won't cost anything extra on the DynamoDB side". You may want to clarify what you mean. You may have been referring to something other than pricing. There is a cost to DynamoDB streams. Every month, the first 2,500,000 DynamoDB Streams read request units are free and then $0.02 per 100,000 DynamoDB Streams read request units thereafter. (N. Virginia)
I have one question: How is this better than having a SNS when the player is playing and then writing in the DynamoDB table and a lambda for the ElasticSearch? I am asking because I see how these DynamoDB events could be useful but what makes them better than directly writing when an event is triggered by the player at the beginning. Thanks!
Amazing explanation. Just 1 question My problem statement was: The bathSize that Aws gives us which can be till 10k , does that mean all shards including 10k or is it that individual shards will have 10k I added batch size as 100 and I see that 100 are not even happening, before that only lambda is hit Note: payload is NOT > 6MB and time is also 300 sec(whihc is not completed) Due to this multiple small files are created in my s3(my lambda does this process), and my etl running on this costs heavily on GET requests. Is there any way around?
Having some background on elasticsearch, and now watched this video and video on GSI, can I have more information regarding when to use dynamodb when to use es?
I have a requirement to stream dynamoDb data to lambda which is in different account. As per the documentation, I can only stream dynamoDb data into the lambda of same account. How can I fulfil my requirement? Can anyone help me out!
thanks for the amazing video! one quick question though - when you say events ordering will be preserved does it mean within shard? As under the hood you explained multiple shards will be created which is acting like a container to store the events, so there is a possibility of situation like E1 -> S1 and E2-> S2?
Video quality of your videos are poor. Sound is low. Increase the sound. If we feel high volume, we can reduce. But, for low volume already, hard to increase.
Hi Andrew. Sorry about that - this was one of my earlier videos where I wasn't aware of audio normalization. If you watch some of my more recent videos you'll notice the quality is much better and sound levels consistent. Thanks.
Hi Peyator, Thanks for the feedback. I definitely agree with you - my audio was horrible in this video. And I do actually live beside a street so good observation on the vehicles haha. I've drastically improved my audio in my more recent videos - this one was one of the first videos I put together for my channel. Hopefully you give them a chance :) Thanks for watching and for your feedback. Daniel

I know I'm going to sound hyperbolic here, but this guy's explanations are quite simply the best I've seen for AWS-related concepts.
Thank you so much John. Your comment means a lot to me. Cheers!
@@BeABetterDev Thank you , you are giifted , not everyone can explain so well !
I agree. Great content
The way you also take up scenario based explanations is phenomenal. Its a great add on apart from the core concepts. Thank a ton :)
You're very welcome!
The same thoughts here, very practical.
I have been looking for a video that will explain dynamodb streams to me in preparation for an exam. This video is prolly the best! This is short but comprehensive
Thanks Sai! Glad you enjoyed.
Concise, yet comprehensive. Its a shame I can only like this video only once?
Thanks so much Eyad for the kind comment. Glad you enjoyed )

That may be a bit complicated for this audience but I'll add it to my list. Sounds like you have quite an interesting project on your hands!
You're really good at this. Keep going!
Thank you so much for the kind words!
Nice to find videos that give use cases and the why's; instead of the how's. thank you !
Glad it was helpful!
This is great, starting a new role and this easily bootstrapped me into the ecosystem
Glad I could help!

Thanks Ujjval! I hope you did well on your interview and that my videos helped you ace it!
Cheers,

This example is amazing, would like to hear more about AWS Elastic Search!
Coming soon! Thanks !
I am surprised that not many people `liked` this video. I work for AWS, and I think this video is very amazing.
Hi G O. I am currently working with DynamoDB. Need your help with “Invalid attribute value type” error.
Thank you G O!
Love the short videos that are to the point with facts and good tips or how the AWS services works. Thank you!
Glad it was helpful!
Respect for this quality of content!
Thanks Auroshis!
Clear and to the point. Perfect!!
Thank you Ashish!

so wonderfully explained, thank you very much !!
You're very welcome!
Great Video! your explanation and examples really made it easy to understand DynamoDB Streams
Great stuff. Just what i need. Thank you, subbed. 👍
Terrific series. Please do one on Route 53.
Thanks ben!
Greate video! Explanations are amazing!
A must watch video
Very useful and informative. 👍
Glad it was helpful!

wow this was so interesting, I understood almost everything

Good point david. I was referring to cost on the dynamodb table itself but you bring up a good point - streams are not free.
you are a Teacher..
I have one question:
How is this better than having a SNS when the player is playing and then writing in the DynamoDB table and a lambda for the ElasticSearch? I am asking because I see how these DynamoDB events could be useful but what makes them better than directly writing when an event is triggered by the player at the beginning.

Perfect 👌 just the voice quality is less good than previous videos..
Not bad if you have headphones on. The content is still as good as ever
Thanks
amazing job
Thanks Abishek!
Can you tell me what's price when using Dynamo db stream with lambda
You are just awesome. Thanks
Thanks Rajesh!
Amazing explanation. Just 1 question
My problem statement was:
The bathSize that Aws gives us which can be till 10k , does that mean all shards including 10k or is it that individual shards will have 10k
I added batch size as 100 and I see that 100 are not even happening, before that only lambda is hit
Note: payload is NOT > 6MB and time is also 300 sec(whihc is not completed)
Due to this multiple small files are created in my s3(my lambda does this process), and my etl running on this costs heavily on GET requests.
Is there any way around?
thank you so much nice video, would like to hear more
Thank you!
please do the implementation after architecture videos, than only it solves the whole purpose. thanks
Having some background on elasticsearch, and now watched this video and video on GSI, can I have more information regarding when to use dynamodb when to use es?
Hi Eric, I'm going to be covering your question in an upcoming video. Check back soon!
The video is really helpful but I did not find the code in the description can you please provide me one
Do you think DynamoDB Stream would be suitable for streaming stock prices to web users who have different watch list?
Dynamodb single table design can cater for quite a large amount of use cases.
I have a requirement to stream dynamoDb data to lambda which is in different account. As per the documentation, I can only stream dynamoDb data into the lambda of same account.
How can I fulfil my requirement? Can anyone help me out!
thanks for the amazing video! one quick question though - when you say events ordering will be preserved does it mean within shard? As under the hood you explained multiple shards will be created which is acting like a container to store the events, so there is a possibility of situation like E1 -> S1 and E2-> S2?
Hi there,
Yes events are preserved, but are bound to the shards. With DynamoDB Streams, the 'shards' map to the DynamoDB Partition Key on your table.
TL;DR - DynamoDB is simply an equivalent to RelationalDatabase Triggers in a more convoluted and expensive way :X
Demn.
Hi can you post some videos on java + lambda
could you provide ppt it would be really helpful!
Excellent material! Clear and concise!
Thank you for the kind words!
audio is low
I swear I fucking love you!
I love you too twisted bam!
Could've used an easier analogy
Video quality of your videos are poor. Sound is low. Increase the sound. If we feel high volume, we can reduce. But, for low volume already, hard to increase.
Hi Jewel, this was one of my first videos. My more recent ones are much better quality.
@@BeABetterDev ok. Got it
Hi welcome to my videos where my audio is really really low.
Hi Andrew. Sorry about that - this was one of my earlier videos where I wasn't aware of audio normalization. If you watch some of my more recent videos you'll notice the quality is much better and sound levels consistent. Thanks.
Please, normalize the audio level...it sounds like you're in a vehicle passing by over and over 🙁 Other than that, good video. 👍
Hi Peyator,
Thanks for the feedback. I definitely agree with you - my audio was horrible in this video. And I do actually live beside a street so good observation on the vehicles haha.

damn the mic is so low volume =_=
Hi there I'm sorry about that - the quality is much better in my more recent videos.
The video is really great but the audio is not up to the mark.
Can you please step it up a notch
Hi Pramesh. This was one of my first videos, apologies for the poor audio quality. The quality in my more recent videos is much better.
@@BeABetterDev Yes sir,
I did see your other videos. I have been binge watching. Loving serverless and your videos. Thank you very much.
very very low audio..
Sorry about this NC. This issue has been fixed in my newer videos.
your voice is very low its better if u can speak some loudly
helpful video #shobhitwalia1
I watched all the videos and this is best playlist on DynamoDb. I have an interview tommorow and they mentioned knowledge about DynamoDb in JD. I hope I crack it and btw keep up the good job.
Thanks
Welcome!
