johanl-db opened a new pull request, #46619: URL: https://github.com/apache/spark/pull/46619
### What changes were proposed in this pull request? Compute the schema of the data without partition columns only once in FileSourceStrategy. ### Why are the changes needed? In FileSourceStrategy, the schema of the data excluding partition columns is computed 2 times in a slightly different way, using an AttributeSet (`partitionSet`) and using the attributes directly (`partitionColumns`) These don't have the exact same semantics, AttributeSet will only use expression ids for comparison while comparing with the actual attributes will use the name, type, nullability and metadata. We want to use the former here. ### Does this PR introduce _any_ user-facing change? No ### How was this patch tested? Existing tests ### Was this patch authored or co-authored using generative AI tooling? No -- This is an automated message from the Apache Git Service.
