Invoke AWS Lambda Function From Another Lambda | Step by Step Tutorial

You must tell how roles are being handled in these lambda functions.

Would have been good for you to discuss why you would need to invoke another function inside this one and the pros/cons of it. Is it an antipattern?

If we can do this directly, what is the use of a step function?

Just a small doubt, are handlers and lambda functions the same?

So much awesomeness!! And absolutely free!

thanks for the explanation. it is very clear. Is it possible to pass query parameters in URL from the invoker lambda to the invoked lambda?

How can I use a lambda function to create a s3 trigger for another lambda function

I only know one Invoker :V

Great video! I have a little question here. I'm facing an issue where I'm generating a report that takes more than 30s so I'm receiving a timeout, due to API Gateway. I've read about async lambdas, but in my case I need the result of the lambda which will generate the report. Basically, the lambda query the data, generates the xls, upload to S3 and return the link to be download from a react app. Do you have any suggestions how to overcome this scenario? Thank you!!

Hey something that is bothering me... in your tutorials its hard to follow the actual important part... writing the code in the lambdas. You seem to skip this a lot. Event vs context? Never explained!

Dude! This video saved me hours of headache, you are the best!!!

Excelent video thanks

Can you make the video about adding layers with AWS lambda C++ runtime..

Thanks, great tutorial

Hellllo!
first of all thanks for the awesome explanation, I got a question though,
can I use the same method to call a lambda function written in Java?
thanks!

thanks

Your lessons are always clear! Thanks.

Hi, just want to ask, does Python runtime supports recursive invocations in Lambda ? currently I have a long running web scraper that needs to run for a very long time to finish, thus need more than 15 minutes for time. Sorry for bothering, btw its a great video.

Simple and precise. So much thanks!

@AWS Simplified I have another question, what would be the best way to execute a java jar file in aws lambda running a python runtime?

@AWS Simplified I have a quick question: Lambda functions have a time out cap of 15 minutes. Say you choose to accept to return response, and child function takes close to 15 minutes, will the parent function timeout?

Thank you!

Your videos are simple and very clear. Thanks

can you post one video same thing via java code

Hi very good tutorial. I am trying to implement a fanout but I have no clue how to do that. My lambda function should invoked for eg. 100 customers simultaneously
Have you a example for me

Thanks in advance 🙏

Hi Thank you For your videos, Sir it will be very kind if you help me to understand this concept like, In Pagination How we can store LastEvaluatedKey in previous Lambda call so that we can pass that value in ExclusiveStartKey in the next lambda call when the front end will call for next set of data? I am facing difficulties to achieve and understand the concept so can you please help me to understand this thing and make one video on that. Thank you so much, sir, appreciate your hard work and talent.

Great video!


But! Why do you need the InvokeAsync permission when you're not calling the LambdaToInvoke asynchronously?


FWIW I have a similar setup where I DO call the other lambda async and it works without that permission.

Thanks !

Hey thank you for your videos, which helped me a lot.
Can you make a video about Lambda Layers?
Modules like Pillow for example are quite tricky, because they don't work properly, if you deploy it on Mac or Windows. You have to deploy it with docker or an EC2-Instance.
This problem drives me crazy :D
