海外TECH	DEV Community	System Design: Google Drive That Scales To The Moon	https://dev.to/shreyanshsheth/system-design-google-drive-that-scales-to-the-moon-2a83	System Design Google Drive That Scales To The Moon IntroductionSo a few months ago I was building a new internal project that helps you upload files like google drive but also works as a CDN so you can use those assets on the front end So here is the few lessons that I have learned along the way RequirementThe project requirement is simply to create a multi tenant app that will let you upload and download files in the workspace ability to make the file public and also make a file available through a single URL with the cache To get file URL will be something like workspaceid key Technology ChoicesStorageFor Storage there are two options mainly S amp R but I have selected S because it s what I have used and it is a more mature solution with most of the issues and solutions online FunctionsI have used the lambda function for it because it works with dynamo DB that I am selecting for file metadataFile Metadatafor file metadata we are storing the mime type size and original name of the file along with indexes that we will talk about later in the blog AuthFor Authentication We Used a simple cookie JWT based system and that won t matter much in the blog context NOTE front end was on react vite Let s Start DesigningWhat We Need to upload a fileto delete the filemake the file publicmake the file available via cdn with cachingin ui workspace users can see all their filesDatabase DesignFor file metadata database design is very simple as it contains query keys as file key and workspaceId as sort and partition keys the reason that workspace id is the partition key is that will help make DynamoDB partition for each workspace and make it more efficient while we query for the list in frontend and file key is the sort key that just helps to make sorting possible with ULID Lexicographically Sortable Identifier as it makes a list on UI based on when it is uploaded and also it is unique so it helps query single files easily For ULID see this blogChart That Represents The DB DesignAs you can see this is the metadata table for the files that we are uploading and this contains all important fields that are required for some or other purpose System DesignFor System Design It Contains Some Part Related To AWSLambda S CloudFront Lambda Edge File Upload ServiceTakes File Type Size and Mimetype save it into a dynamo and Returns POST upload URL that helps upload the file directly to s from frontend with some max age File Delete CRONThis function is a CRON scheduled that will delete files from the s periodically from deleteAfter amp isDeleted as it uses GSI Field from table and also from DynamoDB the ideal time for us is days so if any recovery comes we can resolve it as soon as possible Get Private FileIt Looks At AUTH Token That Represents The Workspace ID and returns a pre sign URL get URL that can help you view the private fileMake File PublicIf the File Is Public It Will Be Served From Cloudfront With Its Caching Layer Also I Have Added Some Image Resizer As A Bonus Part There Here Is The Basic System Design Chart That Helps You Get a Top View Of The Things The EndIf You Like This Article Please Consider Following Me On LinkedIn And If You Have Some Cool Project Like This Just Contact Me I Would Love To Work With Awesome People And Projects Linkdin	2023-05-08 19:38:02
