clauganxo in Catalan, or alcayata in Spanish is what in English is called "hook??".
Is the thingy that you put in the wall when you want to hang something, for example a picture.
We have an application that relies on Amazon S3 as the image storage, once day we received a bill with high transfer costs coming from AWS, taking a look we saw that everything came from the images and all the calls that were done to S3 in order to serve them.
With this service we reduced the API calls and the transfer costs to S3, instead of making Amazon serve our images everytime, we're storing them locally and then serving them.
This service is built with the intention to serve ONLY IMAGES.
tldr: we didn't want to pay high s3 costs and we've built a local cache with go
This service gets objects from the desired s3 bucket, it gets stored at the desired cache directory and then it's served.
You start the service with your custom configuration and then request your image at http://yourclauganxoservice.com/c/object.png
That's it!
All objects are served from /c path
You can also manually flush an object by sending a DELETE request to http://yourclauganxoservice.com/flush/object.png and the file will be deleted from your disk, just in case you don't want to use autoflush.
