[@duyhieu7820]

8:22 - create role 9:13 - specify action 11:47 - lambda 23:29 - example code for getItem 26:11 - use json instead of dynamo json 29:52 - async / await 33:17 - put

[@MichaelRainabbaRichardson]

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

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.

[@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!

[@subhojeetsinha7865]

[@firattamur1682]

Best tutorial for lambda after long time of searching. Thank you!

[@BlockExplorerMedia]

Love to hear that...thanks for the feedback!

[@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

[@caiotony2037]

Thanks too much!!! My permanency in my current job was saved

[@BlockExplorerMedia]

That's awesome...glad to hear that!

[@drvoip]

Excellent material! Most other folks say "Dine a Moe DB" !

[@BlockExplorerMedia]

thanks! i know somebody else pointed that out too, lol. trying to retrain my brain my mangled pronunciation : )

[@denkling]

Why is your video much better than the official AWS-videos?

[@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.

[@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!

[@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!

[@leastros927]

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!

[@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.

[@ritanshusingh4426]

You are a gem....... perfectly explained...love from india ❤️

[@maryotoole8270]

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

[@richardnguyen6141]

Excellent explanation. I like your exceptional teaching skill.

[@arunkumark]

Cool Video!! Explained Lambda & Dynamo DB working in excellent way!

[@fanggladys9986]

exactly agree with Jacari. Also your voice is beautifully soothing

[@johnblack8178]

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

[@johnduriman8662]

Thank you for this, it was very easy to follow. Well made man!

[@kokoro5051]

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

[@emmanuelwafwana5583]

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

[@dkkektmsnsndm2084]

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

[@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?

[@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.

[@MrJohn360]

Got so much value out of it, thanks for sharing.

[@leo5n]

very helpful for me to understand the basic operation of AWS.

[@TheSmellOfCode]

Awesome videos. I like the pace and amount of details.

[@BlockExplorerMedia]

thanks, appreciate it : )

[@kamalbuqaileh8474]

You saved my day, THANK YOU SOOOO MUCH

thanks man, im rookie in AWS and have to create app here :D great tut

[@andreapirola2737]

AMAZING! You are perfect to explain this

[@BlockExplorerMedia]

thanks Andrea...appreciate the support!

[@responseready7375]

You saved my day! I love you :)

[@ManuelSavino]

Wow Amazing! You should honestly produce more content! Like another comment said, would definitely buy a Udemy course or any type of course from you.

[@agnieszkadrabczyk4917]

Thank you so much for your videos. Your vioce is amazing and you explain very well. Thanks

[@zachwhite8054]

Unreal tutorial. Thank you so much. Liked and subscribed.

[@Hackenbaker]

Excelent!! More than excelent. Thanks for this class!!!

[@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 ;)

[@ankitsmit19]

Very nicely explained. Thanks for the tutorial.

[@reprovedcandy]

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

[@q1dsdsdsq2dssdsd95]

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

[@shouldicallyoumista1167]

Very well explained. Subbed!

[@yogirajkouskiya1199]

Good. Thanks for the video. Appreciated.

[@ankur_upadhyay_]

Thank you ... it was amazing lesson and a detailed one ...appreciate

[@madChileRiver]

Great tutorial/demo - thank you very much.

[@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

[@build2scale579]

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

[@prakharbakshi7627]

i cant able to put and get data from dynamoDB please help?

[@himadrithaker4857]

Well explained every steps.. thanks

[@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?

[@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.

[@aakashkharche9429]

Really Helped me alot👍

[@padmavatibasarkode885]

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

[@bunyaminmercan5077]

Awesome Tutorial. Super!

[@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

[@sasquatch2267]

Thanks for creating this! :)

[@robinkelmen6332]

Great videos!!! Thank you so much.

[@shahinanishad2258]

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

[@my.code.studio]

help log wont show up in lambda functions after test cant see the table details, only shows { "statusCode": 200, "body": "\"Hello from Lambda!\"" }

[@musamofomate3825]

Before you test, save your script, then Deploy the changes and then test. I think the problem was not deploying before you test. Hope this helps.

[@paothanh1344]

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

[@wenhuiluo1900]

thank you, sir, this is very helpful.

[@cuzbo_]

Thanks for this. Great tutorial!

[@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.

[@godwincodes]

Very helpful video! Thanks

[@hacmia8708]

Fantastic tutorial, Thank you!

[@keithkinyua6815]

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

[@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)

[@jjurksztowicz]

Very nice tutorial. +9000

[@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

[@illbet4589]

GREAT VIDEO ! Thank you.

[@erlanggarakasatria9652]

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

[@ralphdoegg]

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.

[@JP-vg8vl]

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

[@ba-en1io]

hey, is this series included in the free tier

[@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?

[@bijarnia_vikash]

Good. Thanks for the video.

[@ntokozomajozi2716]

Great tutorial, thank you.

Great Video Mate!

[@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!

[@XGazudin]

boy has this chanegd. the aws impor doesn't wor anymore implicitly, which is the only reason i am frantically searching for a way to get this to work. Whywould they remove the abiliy to just import the aws sdk in the lambda?

[@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

[@filipvranesevic8722]

which font is this in VSCode?

You saved my life

[@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!

[@RaulGlasgow]

code doesnt work. apparently the amazon sdk was updated

[@BlockExplorerMedia]

hi Raul, thanks for the head's up. which part specifically doesn't work? I'll rerun my code as soon as I get a chance and update it if necessary.

[@RaulGlasgow]

@@BlockExplorerMedia i had to use this 'use strict' const AWS = require('aws-sdk'); AWS.config.update({ region: "us-east-1"}); exports.handler = async (event, context) => { const documentClient = new AWS.DynamoDB.DocumentClient({ region: "us-east-1"}); var params = { TableName: "customers", Key: { "id": 2 } }; try { const data = await documentClient.get(params).promise(); console.log(data); } catch (err) { console.log(err); } };
