# Which issue does this PR close? - Part of #5853 - Closes #8517. # Rationale for this change A good bit (around 15%) of Parquet metadata parsing involves first decoding to thrift structs (`FileMetaData`, `RowGroup`, etc), and then converting to the metadata structs used by this crate (`ParquetMetaData`, `RowGroupMetaData`, etc). This PR removes some of the intermediate structures and parses straight to the crate structs. # What changes are included in this PR? Some thrift generated structures are removed, and the code necessary to decode has been hand written. This will enable future optimizations such as selectively decoding parts of the metadata. In addition to the above, this PR cleans up some of the memory size computation, and also boxes some of the objects used for decryption. # Are these changes tested? Should be covered by existing tests. # Are there any user-facing changes? No, only private APIs are changed. -- This is an automated message from the Apache Git Service.
