After compression (20 Oct), this post covers object storage: key layout, lifecycle tiers, versioning, presigned access, multipart cleanup, consistency, encryption and ops metrics.

वस्तुभण्डारधर्मः: A Metrical Codification of Object Storage (with English glosses)

What this post is about

Object storage keeps immutable-ish blobs under keys with HTTP APIs lifecycle rules and durability features.

Topics covered

1. Why not only disks
2. Key layout and hotspots
3. Lifecycle tiers
4. Versioning / guarded delete
5. Presigned access
6. Multipart cleanup
7. Consistency models
8. Encryption custody
9. Inventory and cost metrics
10. Links to upload CDC lakes

Sanskrit title

वस्तुभण्डारधर्मः = vastu-bhaṇḍāra-dharmaḥ “dharma of the object store”.

English

Minimizable; Sanskrit-first.

ग्राह्यम् / Keep

१. prefix design: avoid hot keys
२. lifecycle rules: hot/cool/expire
३. versioning: recovery aid
४. short presign: least privilege
५. abort multiparts: cost control
६. encrypt + key policy: custody clear
७. metrics: requests errors growth

त्याज्यम् / Avoid

• public-read on sensitive prefixes
• no lifecycle ever
• leave incomplete multiparts forever
