01

Tenant-Isolated Uploads — STS credentials generation

Generate temporary, scoped AWS STS keys dynamically. Secure uploads bypass application servers and write directly to tenant-restricted S3 space.

fig 01 · sts credentials generation client upload init GET /v1/files/upload-key org_id: org_01 AWS STS Key Scoper requests temporary AWS credentials · locks session prefix to org_id policy = { prefix: 'tenant_org_01/*' } scoped STS credentials ✓ valid for 15 minutes direct upload authorized

High performance gates live

Scaled to process inbound workloads in sub-100ms with strict rate-limits protections.

Idempotency safeguards live

All writes request carrying idempotency keys are deduplicated instantly at API gateways.

Row-Level Security live

Database layer RLS policies isolate organization records from adjacent workspaces.

02

Pluggable Storage Backends — AWS S3, Cloudflare R2 & Local filesystem

Switch storage systems seamlessly. Swap from AWS S3 in production to local filesystem directories in staging with zero code modifications.

Image & File Pipeline — automated compression & WebP transformation

Resize, crop, and convert images on the fly. Compress large PDFs automatically during ingestion to optimize disk footprint.

Sharing Policies — Row-Level Security scopes

Enforce document boundaries directly in the database. PostgreSQL RLS shields document records and metadata, blocking cross-tenant reads.

Multipart Uploads Orchestration — large file partition gates

Split huge files up to 5TB into smaller chunks. Orchestrates concurrent multipart chunk ingestion and handles failures gracefully.
