itholic opened a new pull request, #43993: URL: https://github.com/apache/spark/pull/43993
### What changes were proposed in this pull request? The PR proposes to refactor data type casting operation - especially `DataTypeOps.astype` - for Categorical type. ### Why are the changes needed? To optimize performance/debuggability/readability by using official API. We can leverage the PySpark API `coalesce` and `create_map `, instead of implementing Python code from scratch. ### Does this PR introduce _any_ user-facing change? No, it's internal optimization. ### How was this patch tested? The existing CI should pass. ### Was this patch authored or co-authored using generative AI tooling? No. -- This is an automated message from the Apache Git Service. To respond to the message, please log on to GitHub and use the URL above to go to the specific comment.
