Wrapper around ParquetObjectreader to provide ParquetMetaData, reading footers from the ObjectStore through a cache-backed reader

Structs§

ParquetReader
Reads a parquet file’s bytes and metadata directly from its object_store (which may itself be L1-cache-backed, see object_cache::l1_wrap) and a shared MetadataCache.
ReaderFactory
A custom [ParquetFileReaderFactory] that handles opening parquet files from object storage, and loads metadata on-demand.
