Object Storage seamless migration

[matt-aitken]

This allows seamless migration to different object storage.

Existing runs that have offloaded payloads/outputs will continue to use the default object store (configured using OBJECT_STORE_* env vars).

You can add additional stores by setting new env vars:

• OBJECT_STORE_DEFAULT_PROTOCOL this determines where new run large payloads will get stored.
• If you set that you need to set new env vars for that protocol.

Example:

OBJECT_STORE_DEFAULT_PROTOCOL=“s3"
OBJECT_STORE_S3_BASE_URL=https://s3.us-east-1.amazonaws.com
OBJECT_STORE_S3_ACCESS_KEY_ID=<val>
OBJECT_STORE_S3_SECRET_ACCESS_KEY=<val>
OBJECT_STORE_S3_REGION=us-east-1
OBJECT_STORE_S3_SERVICE=s3

Walkthrough

Replaces the R2-specific object-store implementation with a new multi-protocol object store module (apps/webapp/app/v3/objectStore.server.ts) and deletes the old r2.server.ts. Import sites were updated to use the new module and callsites now capture returned stored filenames. The new module provides protocol-prefixed URI parsing/formatting, a protocol-aware client registry, upload/download/presign APIs, and support for a configurable default upload protocol. Environment examples and documentation were extended with OBJECT_STORE_DEFAULT_PROTOCOL and protocol-prefixed provider variables (e.g., OBJECT_STORE_S3_*, OBJECT_STORE_R2_*).

Estimated code review effort

🎯 4 (Complex) | ⏱️ ~60 minutes

🚥 Pre-merge checks | ✅ 2 | ❌ 1

❌ Failed checks (1 warning)

Check name	Status	Explanation	Resolution
Docstring Coverage	⚠️ Warning	Docstring coverage is 40.00% which is insufficient. The required threshold is 80.00%.	Write docstrings for the functions missing them to satisfy the coverage threshold.

✅ Passed checks (2 passed)

Check name	Status	Explanation
Title check	✅ Passed	The title 'Object Storage seamless migration' directly and clearly describes the main change—adding support for seamless migration to different object storage providers with multi-provider configuration.
Description check	✅ Passed	The description provides a clear overview of the feature (seamless migration, multi-provider support, env var configuration) and includes a practical example, but is missing several template sections including explicit testing steps, a formal changelog entry, and the contributor checklist.

_{✏️ Tip: You can configure your own custom pre-merge checks in the settings.}
