Open tables and interfaces

Open tables and open interfaces. Attach your tools, build your apps, stream your events.

Lakehouse

Expose Delta, Iceberg, or Hudi-style tables with ACID, schema evolution, and time travel. Register in your catalogue. Share without copying.

invoices-fact.sql

-- invoices_fact (Iceberg-style)
invoice_id STRING, party_id STRING, po_id STRING,
total DECIMAL(18,2), currency STRING,
posted_at TIMESTAMP, effective_from TIMESTAMP, version INT
PARTITIONED BY (bucket(64, party_id), days(posted_at))

SQL

Attach with DuckDB, Trino, Spark.

DuckDB

ATTACH 's3://dbsof/catalog' (secret='...');

Trino

CREATE SCHEMA dbsof WITH (location='s3://dbsof/catalog');

Spark

spark.read.format('iceberg').load('dbsof.invoices_fact')

Graph/GraphQL

Typed relations mirror the ontology. Schema registry entries back each Graph endpoint, so contracts stay explicit.

Use the same order-trace.graphql query from the model page.

Graph mutations respect versioning and provenance, keeping operational writes deterministic.

REST

FRAND REST endpoints mirror canonical objects and events.

rest-api.http

GET /v1/orders/{id}
GET /v1/orders?party_id=...
POST /v1/events (content-type: application/json)
Authorization: Bearer <token>

Streams/CDC

Zero-copy, policy-aware CDC feeds. Filter by object, field, tenant, or enrichment tags to drive downstream systems without duplication.
