Namespace kedro-datasets

[merelcht]

Description

As discussed in Technical Design the kedro-datasets package should be namespaced to kedro.datasets

Implementation

To enable namespacing edit setup.py: https://packaging.python.org/en/latest/guides/packaging-namespace-packages/#native-namespace-packages

• When we do the namespace package for kedro-datasets, we also need to rename the current namespace from kedro_datasets.datasets -> kedro.datasets.

These 2 links will be useful for this ticket

• Mixing of namespace package and non-namespace package
  • Mixing namespace/non-namespace packaging is not advised, but possible. Should we also make kedro a namespace package in this case?
  • The key different is you omit the __init__.py and let setuptools to do the works to figure out where is the package
• Python Standard Doc for namespace package

While doing this, we should make sure these still works

import kedro
from kedro.datasets import *  # From kedro-dataset
from kedro.io import *  # From kedro

After a discussion during technical design, we have concluded that namespacing is not the correct approach for the kedro-datasets split. Further details and discussion can be seen under #1758.
