Execute the Lambda function which will cause it to create a new ENI in the subnet. The function is able to access an RDS database in the VPC. Manually detach

问题 For a Kinesis stream, I created a proxy API using AWS API Gateway. I added a custom authorizer using python Lambda for the proxy. After publish of lambda function and deploy of API, I was able to successfully test the API using Gateway Test functionality. I could see the logs in cloudwatch which had detailed prints from custom auth lambda function. After successful authentication, API Gateway pushed the record to my Kinesis stream However when I call the same API from Chrome Postman client, I

问题 Scenario : create a lambda and it will be triggered whenever a message comes to SQS(let's assume SQS-A).

问题 Following the answer here: https://github.com/aws/aws-sdk-ios/issues/357 At the very bottom there is a mini guide on getting swift and cognito working.

问题 I have a lambda function that queries some DynamoDB tables and returns some entries in them. Invoking it a few times and all is fine, but I am now stress testing my back end and when I invoke this function over and over in a short period of time, I get the following error: "errorMessage":"unable to create new native thread","errorType":"java.lang.OutOfMemoryError" I am using DynamoDB's spatial indexing capabilities, and the error message seems to be suggesting that a line to do with the
