ObjectDB s3-core-v1 compatibility rows

Capability	Status	Maturity	Notes	Evidence	Last reviewed
Service and bucket lifecycle	Supported	Live	ListBuckets, CreateBucket, HeadBucket, GetBucketLocation, and DeleteBucket for empty buckets are active in the s3-core-v1 gateway.	ODB-EVID-002 ODB-EVID-007 DOCS-029	2026-08-16Due 2026-09-30Current
Object PUT, GET, HEAD, DELETE, and copy	Partial	Live	Object routes are active, but PutObject is capped at 16 MiB in the temporary local adapter and delete behavior uses local delete markers.	ODB-EVID-002 ODB-EVID-007 DOCS-029	2026-08-16Due 2026-09-30Current
ListObjectsV2 and DeleteObjects	Partial	Live	ListObjectsV2 uses the temporary ordered-index adapter. DeleteObjects is capped at a 1 MiB body and 1,000 keys.	ODB-EVID-006 ODB-EVID-007	2026-08-16Due 2026-09-30Current
Multipart upload lifecycle	Partial	Live	CreateMultipartUpload, UploadPart, UploadPartCopy, CompleteMultipartUpload, AbortMultipartUpload, ListParts, and ListMultipartUploads are routed through temporary local multipart state.	ODB-EVID-002 ODB-EVID-007	2026-08-16Due 2026-09-30Current
Object tags and user metadata	Partial	Live	Object tagging routes and user metadata are active with local adapter caps: 10 tags, 128-byte tag keys, 256-byte values, and 2 KiB aggregate metadata budgets.	ODB-EVID-002 ODB-EVID-007	2026-08-16Due 2026-09-30Current
Bucket CORS and preflight	Partial	Live	PutBucketCors, GetBucketCors, DeleteBucketCors, and OPTIONS preflight are active through process-memory local bucket configuration capped at 64 KiB and 100 rules.	ODB-EVID-002 ODB-EVID-007	2026-08-16Due 2026-09-30Current
Bucket policy	Partial	Verification Required	PutBucketPolicy, GetBucketPolicy, and DeleteBucketPolicy are active through local bucket-policy state capped at 20 KiB. Customer credential and policy composition remains review-bound.	ODB-EVID-002 ODB-EVID-007 ODB-EVID-009	2026-08-16Due 2026-09-30Current
SSE request headers and encryption identity	Partial	Verification Required	SSE headers are validated and mapped into ObjectDB encryption identity. Encryption-at-rest backend composition remains a separate evidence path.	ODB-EVID-007 DOCS-029	2026-08-16Due 2026-09-30Current
Presigned requests and delegated browser POST	Partial	Verification Required	SigV4 and delegated checks are source-backed for the local gateway. Browser POST uses the PutObject local cap plus a 64 KiB form envelope.	ODB-EVID-002 ODB-EVID-007 DOCS-029	2026-08-16Due 2026-09-30Current
Versioning, Object Lock, lifecycle, replication, inventory, notifications, SelectObjectContent, ACLs, and website hosting	Unsupported	Verification Required	These advanced S3 families are outside the active s3-core-v1 profile and return explicit NotImplemented responses.	ODB-EVID-002 ODB-EVID-006 ODB-EVID-007	2026-08-16Due 2026-09-30Current
Customer credential and authorization parity	Verification Required	Verification Required	The local gateway derives development principals and operation permissions from ObjectDB-specific headers while broader customer credential composition matures.	ODB-EVID-007 ODB-EVID-009	2026-08-16Due 2026-09-30Current
Native ObjectDB object versions, manifests, policies, placement, and events	Preview	Preview Contract	Native object-platform language stays in preview-contract territory until public references and reviewer-accepted evidence land.	ODB-EVID-001 ObjectDB product hub	2026-08-16Due 2026-09-30Current
Additional S3 compatibility profile families	Future	Future	Later S3 profile breadth is roadmap direction only. The current page documents s3-core-v1.	ODB-EVID-002 PROJECT_MANAGEMENT.md	2026-08-16Due 2026-09-30Current

Local Adapter Limits

Explicit Exclusions

Requests for versioning, Object Lock, lifecycle, replication, inventory, notifications, SelectObjectContent, ACLs, and website hosting are outside the active profile and should return S3-shaped NotImplemented responses.

Evidence

Internal review records track this ObjectDB compatibility matrix and the evidence required to change row status.

Limits

This matrix covers ObjectDB s3-core-v1 only. Do not use it to expand advanced S3 family claims, customer credential commitments, or operational outcomes beyond the cited evidence.

See the S3 and HTTP reference for route shapes and the ObjectDB evidence index for review status.
