Fixes polars update which modifies enable_string_cache and broke ACES dataloading

Walkthrough

The change involves a modification to the function call for enabling string caching in the Polars library within the dataset_polars.py file. The specific alteration is the removal of the explicit boolean argument from the function call, which now relies on the default behavior of the pl.enable_string_cache() function.

Line range hint 1-1421: Overall impact of the change and suggestion for testing

The change to pl.enable_string_cache() on line 36 is the only modification in this file. While this change is unlikely to directly affect other parts of the code, it's important to ensure that string handling throughout the file remains consistent with the expected behavior of the string cache.

Given the complexity of the data processing logic in this file, I recommend the following:

1. Conduct thorough testing of all string-related operations in the file, particularly focusing on:

   • Categorical column handling (e.g., lines 1144-1147, 1236-1239)
   • String manipulation operations (e.g., lines 1268-1275)
   • Any performance-critical sections that involve string processing

2. Run the existing test suite (if available) to ensure that all functionality related to this file still works as expected.

3. Consider adding specific unit tests for string caching behavior if they don't already exist.

4. Monitor the performance of string-heavy operations in your application, as changes to string caching can potentially impact performance.

The rest of the file appears well-structured and follows good coding practices. No other changes are required as a direct result of the modification to pl.enable_string_cache().

36-36: Verify the impact of removing the explicit argument in pl.enable_string_cache()

The change from pl.enable_string_cache(True) to pl.enable_string_cache() removes the explicit boolean argument. While this likely relies on the default behavior of the function, it's important to ensure that this change doesn't alter the intended functionality.

Consider the following:

1. Verify that the default behavior of pl.enable_string_cache() is equivalent to pl.enable_string_cache(True) in the version of Polars being used.
2. Add a comment explaining why this change was made (e.g., "Simplified call to enable_string_cache as True is the default behavior").
3. If this change is due to a Polars version update, consider updating the project's documentation or requirements to reflect the minimum required version.

To confirm that this change doesn't affect the behavior, you can run the following script:

This script will output the Polars version and check if the behavior of enable_string_cache() is the same with and without the explicit True argument.

Chat

There are 3 ways to chat with CodeRabbit:

• Review comments: Directly reply to a review comment made by CodeRabbit. Example:
  • I pushed a fix in commit <commit_id>, please review it.
  • Generate unit testing code for this file.
  • Open a follow-up GitHub issue for this discussion.
• Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
  • @coderabbitai generate unit testing code for this file.
  • @coderabbitai modularize this function.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  • @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
  • @coderabbitai read src/utils.ts and generate unit testing code.
  • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
  • @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.
