etlantic-sqlmodel
Optional bridge between ETLantic Data contracts and
SQLModel table models, plus optional CP1
control-plane reference stores. Install when you need contract_to_sqlmodel
helpers or SQLModel-backed definition/submission stores for local CP1 demos.
Package version is 0.47.0 — pin with core.
Install
pip install 'etlantic-sqlmodel==0.47.0'
# pip install 'etlantic==0.47.0'
Schema bridge
from etlantic import Data
from etlantic_sqlmodel import contract_to_sqlmodel, compare_metadata
class Customer(Data):
customer_id: int
name: str
CustomerTable = contract_to_sqlmodel(
Customer,
table_name="customer",
primary_key=("customer_id",),
)
assert compare_metadata(Customer, CustomerTable).valid
Control-plane reference stores (CP1/CP2)
Request-scoped sessions and SQLModel-backed DefinitionRepository /
SubmissionStore / CP2 RegistryProvider implementations. Persistence models
are separate from HTTP response models. create_control_plane_tables and
create_registry_tables are for tests and local demos only — production must
apply versioned migrations via etlantic_sqlmodel.migrations (do not use
create_all as the sole schema path).
from etlantic_sqlmodel.control_plane import (
SQLModelDefinitionRepository,
SQLModelSubmissionStore,
SqlModelRegistryProvider,
create_sqlite_engine,
)
from etlantic_sqlmodel.migrations import apply_migrations
engine = create_sqlite_engine("sqlite:///cp.db")
apply_migrations(engine) # CP2 registry tables (001_registry_cp2)
registry = SqlModelRegistryProvider(engine)
definitions = SQLModelDefinitionRepository(engine)
submissions = SQLModelSubmissionStore(engine)
Registry conformance (memory vs SQLModel promote/suspend):
uv run python scripts/check_registry_conformance.py --fake
These stores honor scoped idempotency and survive process restart when backed
by a durable database URL. For CP-GA Supported profiles, treat snapshots as
canonical for backup/restore; entity dual-write rows are denormalized mirrors
for isolation queries. Use separate engines/schemas per tenant for
isolated-deployment / dedicated-schema.
