Do you pay for metadata accesses? Does running a `find` across the filesystem cost anything? What about system calls that don't transfer data? Can I move or rename a file without paying to copy and then delete the associated S3 object?
- huntaub 2y agoToday, we only charge for cache usage (storage) and data transfer between Regatta and S3. If your metadata access doesn't require transfer to S3, then it doesn't cost anything! However, renames do require transfer to S3 (because we have to move the object on the backend).
- hades32 2y agodoes that mean you pay for the storage twice (i.e. S3 and Regatta) or is the cache size tunable?
- huntaub 2y agoThat’s correct — you pay for the storage yourself in S3, and then you pay for the storage when it’s in the Regatta cache. We may expose the ability to limit the cache size in the future for teams who need controllable costs more than the highest performance.
