aws-sdk | Using vertx-client for AWS SDK v2 | AWS library

i am writing a simple nodejs kinesis producer client which fails with no helpful information. Here's the code:

I tried every possible solution on the internet with no hope

What I am trying to do is simply use aws lambda functions (through the aws console) to fetch user fcm token from lets say DynamoDB (not included in the question), use that token to create endpointArn, send push to that specific device

I tested to send Using SNS console and the push gets to the device successfully but I failed to get it to the device using Lambda functions although it gives success status and message ID

Here is the code I used

After defining class CognitoPool saving it as cognitoPool.ts script:

I'm trying to implement a DynamoDB get_item call using https://github.com/aws/aws-sdk-ruby/blob/0465bfacbf87e6bc78c38191961ed860413d85cd/gems/aws-sdk-dynamodb/lib/aws-sdk-dynamodb/table.rb#L697 via our Ruby on Rails app, dr-recommends.

From reviewing this DynamoDB CloudFormation stack that I wrote, I expect the following get_item call to work, so I'm a little lost as to how to proceed.

AWS recently introduced S3 Object Lambda, however looking at the online documentation:

• Writing and debugging Lambda functions for S3 Object Lambda Access Points
• Introducing Amazon S3 Object Lambda – Use Your Code to Process Data as It Is Being Retrieved from S3
• How to use Amazon S3 Object Lambda to generate thumbnails

I can only find example for Java, Python and NodeJS.

Is there an example out there for c++ that I missed ? In particular I fail to understand what is the equivalent in c++ for getObjectContext (python/nodejs) / S3ObjectLambdaEvent (java) ? How should I retrieve outputRoute, outputToken, inputS3Url ? The integration test does not make it particularly clear either:

• https://github.com/aws/aws-sdk-cpp/blob/main/aws-cpp-sdk-s3-integration-tests/BucketAndObjectOperationTest.cpp#L580-L581

Please help, I've been defeated by AWS...

I have a lambda with the following permissions.

Neither sqs resource-based policy nor the service role has any Deny statements. The lambda should send a message to another SQS queue but it can't, instead I just get this error

Looking at the Using global state section in the official AWS Lambda function handler in Go doc https://docs.aws.amazon.com/lambda/latest/dg/golang-handler.html

suggests to initialise all global state in func init() i.e. Any package level vars which we want to share across multiple lambda invocations go here.
And my understanding is that this initialisation is done once per lambda container start (i.e cold start).

My question is, is it possible to do the same using func main() instead of func init().
Using func init() basically makes my handler function (func LambdaHandler) non unit-testable due to side-effects from func init() running.
Moving the func init() code to func main() seems to solve this easily.
Are there any side effects to using func main() vs func init()

I have a question on the step function part of AWS

I have a function to watch and update datas in databases. But because we can have only 1000 as we can have 1 000 000 items to update, I would like to manage it by 10 000 or 100 000 with a lambda.

But the optimal solution should be to manage them in parallel to update every datas at the same time and finish them together

So for that I would like to create a Lambda function with aws-sdk which should create a parallel step function with X tasks and every tasks will manage 10 000 or 100 000 items of the database

But when I read the aws-sdk documentation, it looks like there is no way to create a parallel step function, even from a template

So my question is, is it possible to create a parallel step function from a Lambda function with aws-sdk ? Or do you have a better solution to my problem ?

Thanks in advance

Update : To give you more informations, my problem is I'll have to update a insert an unknown of datas in my DB each first day of month, and the problem is that I need to call an API that takes 15 seconds to return the data (it's not our API so I cannot try to upgrade return time).

If I just use a Lambda function, it will be in timeout after 15 minutes.

Suddenly, I thought of using Step function to execute the Lambda function for each data, but the problem is, if we have a lot of datas, it will maybe take more than 24 hours and I would like to find a solution where I can execute my Lambda function in parallel to optimize the time, so i thought about parallel task of step function.

But because the number of datas will change every month, I don't know how to dynamically increase or decrease branch number of my step function, and that's why I thought of generate my step function from another Lambda

I've been having a heck of a time trying to access the new Amazon SP-API with the Ruby gem amz_sp_api

I've followed all the directions on creating an IAM user as well as getting what I believe are the correct tokens.. But I continue to get the following error:
