One of the easiest ways I used to upload files to S3 using Lambda is to convert it to a base64 encoded string and pass it to the buffer and then to the s3 putObject method and it’s as simple as Usually to unzip a zip file that’s in AWS S3 via Lambda, the lambda function should 1. Read it from S3 (by doing a GET from S3 library) 2. Open it via ZIP library (via [code ]ZipInputStream[/code] class in Java, [code ]zipfile[/code] module in Pyt In this video, we will look at how we can add a file 4 different ways to our S3 Bucket 1 - Simple file upload 2 - Upload with an explicit filename 3 - Upload data from a type of System.IO.Stream 4 Suppose you want to create a thumbnail for each image file that is uploaded to a bucket. You can create a Lambda function ( CreateThumbnail ) that Amazon S3 can invoke when objects are created. Then, the Lambda function can read the image object from the source bucket and create a thumbnail image target bucket. Download the incoming file in /tmp/ Run ClamAV on the file; Tag the file in S3 with the result of the virus scan; Lambda Function Setup. Create two lambda functions, make sure to select a runtime of Node.js 8.10 or above as well as a role that allows you to read and write to S3 bucket. Upload the zip file for both functions. Once the CSV files are uploaded to S3, we can easily access them from the Lambda. However, to read the CSV file in the Lambda we will need to download the file to the Lambda and then parse it to

However, to read the CSV file in the Lambda we will need to download the file to the Lambda and then parse it to Users upload multiple files direct to Amazon S3 (im using carrierwave). I'd like Users to have the abililty to download a Projects datafiles as a single zip file. Im trying to figure out the best strategy to implement this feature.
