In this project we explore how to upload files to an S3 bucket and add specified tags to them.

I created this project previously but used ElastiCache as the temporary storage for configuration. This time I am using DynamoDB with TTL. You might ask, why then not just use DynamoDB to store all the information about uploaded images? My answer is very simple: tags are free!

The previous version of this project is here: https://github.com/ppabis/s3-presigned-tagging. But I decided to start a new repository to keep everything cleaner. Now you don't have to install any requirements as we will be using only boto3.
