    How do I enable a code linter in my repository?

    You can uncomment the lines related to lints in the transforms-python/build.gradle in your code repository. This will enable a linting task that will provide hints to violations of either pep8 or pylint format rules.

    How can auto-scaling of executors be achieved in Spark profiles for dynamic scaling based on transform input sizes?

    Auto-scaling of executors can be achieved by enabling dynamic allocation, which allows for auto-scaling of executors but not for executor/driver memory. Specific profiles such as DYNAMIC_ALLOCATION_MAX_64 and the DYNAMIC_ALLOCATION_ENABLED profile support this functionality. More information and a list of profiles with built-in configurations for dynamic allocation can be found in the Spark profiles reference documentation.

    How do I enable an auto formatter in my Python code repository?

    Selecting the Format before committing option when committing code will run the formatCode task. This task can utilize ruff or black as formatters. This can be controlled by uncommenting the respective lines related to formatters in the transforms-python/build.gradle file.

    What steps should be taken to troubleshoot and resolve an import error stating No module named <module-name>; <package-name> is not a package in a transform?

    To troubleshoot and resolve the import error, follow these steps:

    1. Verify the library installation and ensure it is correctly installed in your code repository.
    2. Check for hidden files and ensure environment configuration is set up properly.
    3. Resolve any package conflicts by reviewing package resolution logs.
    4. Re-trigger environment resolution by making a new commit if necessary.
    5. If the module worked before but stopped working, check the version differences in the library for any major breaking changes.

    In transforms, what is the correct method to write a pandas dataframe?

    To write a pandas dataframe, you should use the .write_pandas() method. If you encounter an AttributeError: 'DataFrame' object has no attribute '_jdf', it means you are using a method designed for pyspark dataframes on a pandas dataframe.
