Which issue does this PR close?
57.0.0(October 2025) #7835Arc<FileDecryptionProperties>to reduce size of ParquetMetadata and avoid copying whenencryptionis enabled #8470Rationale for this change
While testing arrow 57 with DataFusion, I found there was a disconnect
in the builders that the
FileDecryptionPropertiesbuilder builds Arc and theFileEncryptionPropertiesbuilder builds the struct directlyLet's make the APIs consistent
This also allows encryption properties to be shared and cloned cheaply (I am not sure how often this is needed, but it seems like a reasonable thing to do)
