Good demo video . Explanation of each and every step is spot on .

Hi there, i have actually run into a problem. when i try to add the lambda trigger into sqs it throws an error message "Error code: InvalidParameterValueException. Error message: The provided execution role does not have permissions to call DeleteMessage on SQS" and i have used the same policy for the sqs as shown in this video. any idea how to solve this?

[@yaminisingh7271]

HI, demn girl you explained it so well. I have a question, if we follow the exact pipeline and in the lambda function write a code to connect to ec2 instance and over that ec2 use the newly added file in s3 bucket input for a python code for some calculation. It should work fine right. For ex : - upload the file in s3 -> sns topic-> sqs que -> lambda -> ec2 (run and connect) -> runs the python file.(command given in lambda function).
correct?

Hi there. This is a very straight forward easy to understand tutorial. Do tell, did the SQS policy change? The policy you posted on Github is different from what I on your screen.

[@listentolearn2363]

Thanks :) please use the policy in GitHub. Thanks

[@nikitanagarkar1643]

Hi , will this work for prefixes within s3 bucket?

[@HemaSri-e5n]

Can we create sns topic without changing access policy to advanced

[@muqtadirahmd]

Hi, great video and thanks for uploading. I have a question. When would I want to add a SNS and SQS service in my architecture when I know I can trigger a Lambda directly from S3? Can you please tell the use cases when it would be helpful to do so. Thanks in advance!

[@listentolearn2363]

Thanks Muqtadirahmd! SNS SQS pattern will help in parallel processing by distributing the messages to various queues based on several attributes.

[@CHiRaStar1]

Exceptional. Very insightful. Is there any possibility of connecting with you discuss about work

[@listentolearn2363]

thanks :) I can reply here..

[@vasugoriya1452]

Why we need to create sns and sqs instead of we can directly invoke lambda from s3

[@basavarajpn4801]

If there are 1000files loaded Into s3bucket lambda can handle only 1000functions in concurrent run at a time ,so if in case there is SQS,sqs holds the messages from s3 events and queues it and passes to lambda to process all files with out any issues

[@listentolearn2363]

Hello, thanks for you interest.. SNS SQS pattern will help in parallel processing by distributing the messages to various queues based on several attributes.

[@denisafonkin8795]

what is the "arn:aws:sqs:::q1" ?

[@listentolearn2363]

that is the arn of the queue. please replace and with actual values

[@bhumikalalchandani321]

Coudnt get how file 2 on reiploaded went to queue2 ....anyone😢...ie by default file queue 1 file2 queuue 2 so onn...

[@listentolearn2363]

Hi, It is because of the Subscription filter policy set in the SNS while adding the queue to it. Pleas see from 14:45 in the video.
