AWS Lambda BATCH Processing From SQS | Powertools for AWS Lambda | .NET ON AWS | Serverless | Amazon

Happy New Year 👋
The AWS Lambda PowerTools Batch processing utility makes it easy to process a batch of messages from Amazon SQS, Amazon Kinesis Data Streams, and Amazon DynamoDB Streams.
It provides a simple interface to process each batch record, enables parallel processing, reports batch item failures to reduce the number of retries, and also supports customizations to meet your business needs and functionality.
In this video, let’s learn how to use the Lambda Powertools Batch processing utility to process messages in batches from Amazon SQS.

Hi Rahul! I'll tell you something about your "subscriptions", in Argentina they appear with the values 20 and 50 Argentine pesos, which are 2 and 5 cents of a dollar, I wanted to let you know in case you want to update them because they are too low.

[@RahulNath]

Thank you Mariano for supporting me this long!! I guess that's youtube doing the conversion automatically, but thank you for letting me know! Hope you are liking the videos.

What is maximum we can use foe the batch size

[@chiragpatel908]

I want to know about how millions of records retrieved from Dynamo and execute long processing within the limits of lambda net core c# and AWS lambda using steps function.

[@RahulNath]

Hey Chirag - What are the issues you are facing with it currently? Planning to do a video on step functions soon

[@chiragpatel908]

@@RahulNath I'm trying to export more than 2 millions records from Dynamo. So after retrieving we have a real time calculation of verifying and creating missing values inside another Dynamo and then exporting in CSV. So that real time calculation process takes time and gives error timeout. How can I divide the whole process into 3 retrieving ,calculation processing, exporting lambdas and design step function architecture to pass that data through one lambda to another. So I can sure not hit lambda limits of 15min. Thank for your prompt response 🙏

[@RahulNath]

@@chiragpatel908 is it the calculation process alone that is throwing the timeout? Is one lambda trying to do the whole 2 million records? I would look at batching them up based on your partition key or whatever makes sense.

[@chiragpatel908]

@@RahulNath Yes. I'm now thinking about the divide into above-mentioned but the problem is how can I pass a large amount of data from one lamba to another and process all records parallelly to reduce time and prepare for the final result for export using step function.

[@RahulNath]

@@chiragpatel908I would store the data in a temporary location (dynamodb, s3 etc ) depending on the nature of data and how the final export is. You could then pass around the identification to that (batch id partition id etc) to the other lambda function. Hard to tell exactly which without knowing more details.

Great Video, but you should also take care of your self. one side of your face is dull Seems like a sinus infection! Stay Healthy.

[@RahulNath]

Glad you like the video and thank you for thinking for me! I am doing well now and did have a blocked nose while recording that day. Have a great day
