[@MichaelRainabbaRichardson]

40:35 forgot to confirm the return on a put after using a unique key.

[@ryanrussell4071]

You have a genuine gift for explaining concepts. Thank you so much for putting this together. I will be sharing this video at an upcoming Hackathon to help attendees set up their Lambda instances.

[@alammahtab27]

Nicely explained. I really like the pace of your explanation, you were calm and not like others who actually rushes to finish it off and make the story short. Well done

[@rainthstrive]

Here I am, at 4am, following and successfully finishing this tutorial pleasantly and with a smile on my face. Sometimes I zone out following lenghty videos, but yours is super cohesive and easy to follow! Thank you so very much.

[@maryotoole8270]

Awesome. This was so much more helpful that the Amazon online tutorials. Big help and thanks so much!

[@reidyoung298]

Thank you SOOOOOO much for this fantastic video. It deservers 10M views and a badge of honor. I appreciate all the effort that went into it. Loved the video. It's inspiring me to create a few of my own. All the best Cloud Path!

[@kokoro5051]

Thanks dude, this series is pretty good and solid. I love it.

[@pragmaticcoder6910]

God bless you! Thanks for giving this tutorial for free. I am preparing for new job and need knowledge on AWS Lambda. May God bless you and your family!

[@ENCRYPTaBIT]

Wow I'm impressed. I'd buy this on Udemy for sure. But you're generous enough to give this out for free. Subscribed and liked!

This was so helpful to me. I truly appreciate the video. It was very clear and concise as well as easy to follow. Thank you for your work!

[@BlockExplorerMedia]

really glad to hear that. thanks for your support!

[@SameeraAbeywickrama]

Wow, I wish I had found this earlier. Thanks man. Very useful and very well explained. I would love to see a tutorial on Serverless framework from you

[@BlockExplorerMedia]

thanks Sameera, glad you found it useful! i do have a 'Create a Serverless App' tutorial series available here: kzbin.info/www/bejne/jHjIo55undeDb7c. anything else you'd like to see covered on this channel?

[@johnblack8178]

Thanks for that great tutorial, you have a nice voice to listen to. Thanks to you i understand the environment better.

[@holyproton8855]

What an awesome tutorial, I learned a lot! Looks like the logs would have displayed the new item created if the ID is unique. With preexisting IDs it shows empty brackets.

[@dkkektmsnsndm2084]

What a clear explanation, thank you sir. I really appreciate all the help you gave. Love respect.

[@emmanuelwafwana5583]

The lesson is great. Probably the best i ever followed. Everything works at the end ;-). Thanks a lot!

[@MrJohn360]

God bless you, fantastic tutorial!

[@no_one1500]

Thankssss complete detailss yet simple and efficient.... Thanksssss alotttt

[@noneofourfinbusiness]

Thanks for the video it helped me over the first hurdles. My next hurdle is to customize the query to return just the fields I want, and also related fields from other tables hopefully just like they do in GraphQL. I can't seem to find samples for lambda code using clientDocument or even the first way you did it. I found some examples using "ProjectionExpression" but...doesn't seem to be working. If you ever do a video on this I would enjoy it ;)

[@bunyaminmercan5077]

Awesome Tutorial. Super!

[@ntokozomajozi2716]

Another vedio on dynamo db core concepts required for production env to create sacalable , high performing db - kzbin.info/www/bejne/o4Sao4Fph9yBhsk

[@illbet4589]

GREAT VIDEO ! Thank you.

[@amberjones6191]

Great teacher!

[@manishpundir28]

Thanks for the awesome video!👍 One question - Shouldn't the ids be auto generated uniquely for a new item? Otherwise how do we ensure not to pass an existing id? Do we need to look into DB each time?

[@jjurksztowicz]

Very nice tutorial. +9000

[@john-danson3113]

Great work! Thanks Mister! Tidy it up. Could be 20 mins.

[@almogcohen2858]

Great videos, thanks alot !

[@MrMrMayday]

You saved my life

[@ayubadan3220]

Great Video Mate!

[@jahongirbozarov3135]

Thank you so much for making this video! Helped me a lot, but could you please show us how to create new record ( I understand if id we are passing doesn't match with any existing user's id it will create new user ) but I was thinking to create lambda function using post not put ? Thanking in advance

[@JangBahadur3028]

Kudos to the guy. Really knowledge ful video.

[@BlockExplorerMedia]

Thanks Jang glad you found it helpful.

[@JP-vg8vl]

thank you for this video!

Thank you! :D

[@prathameshmahangade8987]

You are the best

[@CTCCCCCCCC]

Thank you so much dude!!!

[@nikwycherley9079]

If you get an error at around 25:35 saying something like "unexpected s found in query" make sure the s in the ID object is set to a capital S.

[@coltonjett5635]

i got a error saying " * MissingRequiredParameter: Missing required key 'HashKeyElement' in params.Key * UnexpectedParameter: Unexpected key 'id' found in params.Key " and i even copied word for word and had capital S driving me nuts.

[@sach695]

This comment needs to be featured or pinned or something.

[@DavidJJJ]

Just a note to say that you no longer need to specify the data type (ie. ‘S’) in your dynamodb object.

[@TheBodysome]

This is awesome, super simple and works out of the box (Ignoring my IAM issues). Do you have a twitter? oh also, Udemy Update?

[@BlockExplorerMedia]

i have a twitter account but haven't been using it much. Udemy...still working on that!

[@simpsonandrew9572]

Good demo! Is there a chance to do a get first and base on the result to do a put to the DB in one js ?

[@q1dsdsdsq2dssdsd95]

thank you for your videos! say, why dynamodb doesnt say that you try to rewrite existing in the table item?

[@JayJugJones]

nice tutorial

[@hmnyari]

thank you so much !!!!!

[@balajikesavan9933]

thats a nice one

[@nand0l]

Hi In this video you are adding an String value, how would you add a "list" for an array or a "Map" for an object?

[@reprovedcandy]

8:29 i love how it recommends the name so you know this wasnt his first take haha

[@sahild6584]

Thnx a ton

[@christophermartinez1769]

Thanks a lot

[@daronwolff]

Thanks a lot

[@paothanh1344]

hi there, how can you get all the data from the database, from this video it seems only get 1 at a time

[@bennychewDev]

Thanks for creating your AWS series, these are very helpful! I'd be interested in a more in depth Udemy course of this if available. Now we are copy pasting the code from local to AWS, I wonder if it is possible to keep writing the Lambda functions locally and with one Terminal command, deploy it to AWS. Or is creating a zip of it the only way?

[@BlockExplorerMedia]

there should be a few options for deploying a lambda without copy/paste or zip upload. hope to cover this in a tutorial video soon.

[@bennychewDev]

@@BlockExplorerMedia I came across Serverless framework couple of days ago. Seems pretty interesting. May be what I was looking for. kzbin.info/www/bejne/gomlY4Gsbt6ah8U

[@keithkinyua6815]

how can i save my results to a postgres DB or dynamoDB after hitting an endpoint via a lambda function

[@oleersoy6547]

You rock!!

[@BlockExplorerMedia]

thanks for watching!

[@HemachandranM]

That was a good session.. I have a very basic question. Is it possible to store an js object like output of `new AWS.TemporaryCredentials( )` in dynamodb using nodeJs implementation? If yes, is there any samples around it.

[@BlockExplorerMedia]

hi Hemachandran, yes you can store a JS object in Dynamo. i just tried to do it this way (from the DynamoDB docs) and it worked ok: docs.aws.amazon.com/AWSJavaScriptSDK/latest/AWS/DynamoDB/DocumentClient.html#put-property Your json object would be the value of the 'Item.MapAttribute' property. The only thing I had to add was an id (my table required it as the primary key)

[@shahinanishad2258]

@Cloud Path, the AWS app course that you mentioned is available now in Udemy?

[@imaxshen]

Hi, I created a new AWS account and followed everything you demonstrated in your video. But when I tried to create a Lambda function, I got "Missing Authentication Token" error. I tried to google the error msg, but almost all the result pages are related to AWS API Gateway. Does anyone hit same issue previously? Any workaround? Thanks a lot

[@kikibonbon86]

At 28:00 I got an error: "self.configure is not a function" And I'm sure I have the exact same code (I checked every line 10 times 😂) Could you help me with that? Great video btw!

[@padmavatibasarkode885]

hey can one lambda perform 2 operations ? for example writing in ddb and sending request to sqs/sts ?

[@RicardoChase894]

The Best

[@BlockExplorerMedia]

Thanks Jiiiiiiiiang!

[@devzhy9687]

If I create a full-fledged app using AWS Lambda, do I have to create many roles and assign them manually for all the functions I create? Seems tiring.

[@ba-en1io]

hey, is this series included in the free tier

[@skkkks2321]

Hi, thank you for this most needed videos series for the Data Engineers, do you have courses in Udemy? please share the link. Thanks for the amazing work.

[@BlockExplorerMedia]

Thanks...planning to do some Udemy courses in the future

[@tigermk_nft]

I notice we hard coded the users in our code, what if we just want to retrieve the data say from an ip without hard coding the user names.

[@erlanggarakasatria9652]

i cant get my item from dynamoDB , and the response is : { "statusCode": 200, "body": "\"Hello from Lambda!\"" } can anyone help ?

[@ralphdoe12]

I think we have a different version of Lambda in Browser. You need to save with File -> Save Option. Then click Deploy. And then you will be able to test successfully.

[@devswami3159]

tq

[@JP-vg8vl]

please make a tutorial on how to send data from AWS IoT to DynamoDB using Lambda
