Kedro

pydantic-kedro

Advanced serialization for Pydantic models via Kedro and fsspec.

This package implements custom Kedro "datasets" for both "pure" and "arbitrary" Pydantic models.

Please see the docs for a tutorial and more examples.

Minimal Example

This example works for "pure", JSON-safe Pydantic models via PydanticJsonDataSet:

from pydantic import BaseModel
from pydantic_kedro import PydanticJsonDataSet


class MyPureModel(BaseModel):
    """Your custom Pydantic model with JSON-safe fields."""

    x: int
    y: str


obj = MyPureModel(x=1, y="why?")

# Create an in-memory (temporary) file via `fsspec` and save it
ds = PydanticJsonDataSet("memory://temporary-file.json")
ds.save(obj)

# We can re-load it from the same file
read_obj = ds.load()
assert read_obj.x == 1
