Why someone would storePDF file in a relational database instanse? And how this is even possible? Why not use S3 or Document DB?
A PDF would not be stored in RDS, but a link to the object in an S3 bucket may be. A use case would be if a lambda generates a PDF in an S3 bucket and puts a link to its location in DynamoDB so when the backend needs the latest PDF, it can point to the needed S3 object.
Take this with a grain of salt, it’s been a while since I was studying for this.
Why do it?: I would imagine storing a DESCRIPTION is more secure from an operational perspective rather than originals. It seems like having the blueprint to build the house vs having the house physical house to copy. idk I have never used an object DB a lot of my work is with relational DBsHow is it possible?: By storing the data that describes the file so it can be rebuilt later: https://docs.aws.amazon.com/AmazonS3/latest/userguide/upload-objects.html
