aws-lambda

问题 There are a few pieces of my app that cannot afford the additional 1-2 second delay caused by the "freeze-thaw" cycle that Lambda functions go through when they're new or unused for some period of time. How can I keep these Lambda functions warm so AWS doesn't have to re-provision them all the time? This goes for both 1) infrequently-used functions and 2) recently-deployed functions. Ideally, there is a setting that I missed called "keep warm" that increases the cost of the Lambda functions,

问题 When decrypting ciphertext from the command line using the AWS CLI, the ciphertext gets decrypted without issues: $ aws kms decrypt --ciphertext-blob fileb://encrypted-secrets --output text --query Plaintext --region us-east-1 | base64 --decode > decryped-secrets This decryption operation also works locally when attempting to do so from a js script: #!/usr/local/bin/node const fs = require('fs'); const AWS = require('aws-sdk'); const kms = new AWS.KMS({region:'us-east-1'}); const secretPath =

问题 I have deployed librosa, matplotlib and all its required dependencies using AWS-Lambda-layers and it's working fine. When I send a .wav file from postman using the binary format the librosa.load() gives me the following error { "errorMessage": "module 'soundfile' has no attribute 'SoundFile'", "errorType": "AttributeError", "stackTrace": [ " File \"/var/task/lambda_function.py\", line 83, in lambda_handler\n clip, sample_rate = librosa.load(file_name)\n", " File \"/opt/python/librosa/core

问题 Very first thing I've ever done in Node.js, I'm writing an AWS Lambda function, and I want to check whether a custom attribute on a User has a value before doing anything else. Since I'm told Promises are the way to handle asynchronous methods synchronously, I wrote the function: var AWS = require('aws-sdk'); var s3 = new AWS.S3(); var cogId = new AWS.CognitoIdentityServiceProvider(); exports.handler = function (event, context) { if (event != null) { var identityId = context.identity
