pyspark-stubs 3.0.0.post3

Description:

pysparkstubs 3.0.0.post3

A collection of the Apache Spark stub
files. These
files were generated by
stubgen
and manually edited to include accurate type hints.
Tests and configuration files have been originally contributed to the
Typeshed project. Please refer
to its contributors
list and
license for
details.

Important
This project has been merged with the main Apache Spark repository (SPARK-32714). All further development for Spark 3.1 and onwards will be continued there.
For Spark 2.4 and 3.0, development of this package will be continued, until their official deprecation.

If your problem is specific to Spark 2.3 and 3.0 feel free to create an issue or open pull requests here.
Otherwise, please check the official Spark JIRA and contributing guidelines. If you create a JIRA ticket or Spark PR related to type hints, please ping me with [~zero323] or @zero323 respectively. Thanks in advance.



Motivation

Static error detection (see
SPARK-20631)


Improved autocompletion.





Installation and usage
Please note that the guidelines for distribution of type information is
still work in progress (PEP 561 - Distributing and Packaging Type
Information). Currently
installation script overlays existing Spark installations (pyi stub
files are copied next to their py counterparts in the PySpark
installation directory). If this approach is not acceptable you can add stub
files to the search path manually.
According to PEP
484:

Third-party stub packages can use any location for stub storage.
Type checkers should search for them using PYTHONPATH.

Moreover:

Third-party stub packages can use any location for stub storage.
Type checkers should search for them using PYTHONPATH. A default
fallback directory that is always checked is
shared/typehints/python3.5/ (or 3.6, etc.)

Please check usage before proceeding.
The package is available on PYPI:
pip install pyspark-stubs
and conda-forge:
conda install -c conda-forge pyspark-stubs
Depending on your environment you might also need a type checker, like Mypy
or Pytype [1], and autocompletion tool, like Jedi.

This package is tested against MyPy development branch and in rare cases (primarily important upstrean bugfixes), is not compatible with the preceding MyPy release.


PySpark Version Compatibility
Package versions follow PySpark versions with exception to maintenance releases - i.e. pyspark-stubs==2.3.0 should be compatible with pyspark>=2.3.0,<2.4.0.
Maintenance releases (post1, post2, …, postN) are reserved for internal annotations updates.


API Coverage:
As of release 2.4.0 most of the public API is covered. For details please check API coverage document.

Footnotes


[1]
Not supported or tested.


[2]
Requires atom-mypy or equivalent.


[3]
Requires autocomplete-python-jedi or equivalent.


[4]
It is possible
to use magics to type check directly in the notebook. In general though, you’ll have to export whole notebook to .py file and run
type checker on the result.


[5]
Requires PyDev 7.0.3 or later.


[6]
TODO Using vim-mypy, syntastic or Neomake.


[7]
With jedi-vim.


[8]
With Mypy linter.


[9]
With Python extension for Visual Studio Code.


[10]
Just use your favorite checker directly, optionally combined with tool like entr.
