What is S3 cache / dbGaP cache?

(s3cache was discontinued in January 2021)

Intended for short-term caching of bulk protected data (e.g., NIH dbGaP data). Consider this a scratch space with a 60-day lifecycle.

No source data; copies only!

Capacity is limited to 400 TB total, shared by all dbGaP users (fairshare). Don’t be a jerk! (Cleanup after yourself)

Bucket ACLs are restricted to individual projects; do not open permissions

If cache capacity is reached, objects are deleted following a First-In-First-Out rule regardless of 60-day lifecycle
