etlantic-sqlmodel 0.21.0

ContractModel ↔ SQLModel bridge for ETLantic.

etlantic-sqlmodel

Optional bridge between ETLantic Data contracts and SQLModel table models for ETLantic 0.20.

pip install 'etlantic==0.21.0' 'etlantic-sqlmodel==0.21.0'
# or: pip install 'etlantic[sqlmodel]'

Sessions, Alembic migrations, and repository helpers are deferred to 1.1+. This package focuses on schema mapping and metadata comparison only.

Usage

from etlantic import Data
from etlantic_sqlmodel import (
    compare_metadata,
    contract_to_sqlmodel,
    create_plugin,
    sqlmodel_to_contract,
)


class Customer(Data):
    customer_id: int
    name: str


CustomerTable = contract_to_sqlmodel(
    Customer,
    table_name="customer",
    primary_key=("customer_id",),
)

metadata = sqlmodel_to_contract(CustomerTable)
report = compare_metadata(Customer, CustomerTable)
assert report.valid

plugin = create_plugin()

This bridge is used explicitly through its public conversion helpers; it does not require a profile engine setting. Register create_plugin() only with tooling that consumes the schema-mapping plugin object.

Generated SQLModel classes are reviewable starting points — relational choices such as primary keys and table names must be supplied explicitly.
