Can someone explain when this would be good solution? We currently store loads of files in S3 and directly ingest them on demand in our Java app API pods. Seems interesting if we could speed up retrievals for sure.
The basic tradeoff is that you are paying an extra tax on all requests that are not served by the cache, so you something like this would help if you are reading the same data repeatedly. So, for example, a database built on object storage or something like that.
