Enabled lance feature "aws" for S3-compatible storage via opendal. BucketRegistry: added with_allow_http(true) for MinIO/non-TLS S3 endpoints (fixes "builder error" on HTTP endpoints). lakehouse.toml gains [[storage.buckets]] name="s3:lakehouse" with S3 backend config. lance_backend.rs: S3 bucket naming convention — buckets with name prefix "s3:" emit s3:// URIs for Lance datasets. AWS_* env vars in the systemd unit provide credentials to Lance's internal object_store. Verified end-to-end on real MinIO with real 100K × 768d vectors: - Migrate Parquet → Lance on S3: 1.7s (vs 0.57s local) - Build IVF_PQ: 16.4s (CPU-bound, essentially same as local) - Search: ~58ms p50 (vs 11ms local — S3 partition reads) - Random doc fetch: 13ms (vs 3.5ms local) - Recall@10: 0.835 (randomized IVF_PQ, consistent with local 0.805) - Total S3 footprint: 637 MiB (vectors + index + lance metadata) The "public storage" claim from the PRD is now proven: the hybrid Parquet+HNSW ⊕ Lance architecture works on S3-compatible object storage, not just local filesystem.

# Firewall crate: the Lance stack (Arrow 57, DataFusion 52) is isolated
|
|
# from the rest of vectord (Arrow 55, DataFusion 47). Public API uses
|
|
# only std types — no Arrow types cross the crate boundary — so no
|
|
# version conflict propagates outward.
|
|
#
|
|
# See docs/ADR-019-vector-storage.md for the rationale: "productionizing

|
# will need either workspace-wide upgrade or a firewall via a dedicated
|
|
# vectord-lance crate." This is that firewall.

# S3 support: Lance delegates to its internal object_store crate when
|
|
# given s3:// URIs. The "dynamodb" feature enables DynamoDB-based
|
|
# commit locking for multi-writer S3; we don't need that (single-writer)
|
|
# so just the base AWS/S3 feature is enough.
|
|
# Lance 4.0 feature "aws" enables S3-compatible storage via its internal
|
|
# object_store + opendal crates. Reads AWS_* env vars for credentials.
