// This script will scan all files in a given directory for locally referenced images. It will take the images, rename them with a standard convention, then upload them to s3 with a 'public-read' ACL. The script will then update the reference to the local image with the link to the version in the cloud.
// If there are any issues during operation, the script will output either a 'skipped-posts.json' file that lists the posts that were not processed or a 'failed-image-uploads.json' file that lists images that failed to upload into S3.

// Arguments for operation
//
// [0] blogPostDirectory - relative path from the root where all blog posts live
// [1] imageDirectory - relative path from the root where all images live
// [2] bucketName - name of the S3 bucket to upload the local images to
// [3] awsProfileName - name of the aws profile on your machine that has access to the S3 bucket

Request batching benchmark

Request batching is a Node.js pattern that can be used to optimise how a web server handles identical concurrent requests.

It allows to process the request only once for all the clients concurrently requesting the same information. This can save expensive round trips to backend services and can avoid backend services to be overloaded with many concurrent identical requests. In a way it's a more specialised version of micro-caching.

This can lead to significant performance improvement in cases where there are many concurrent users requesting the same page.
