Package: qio 0.1.1.9000
qio: Read and Write 'Apache Parquet' Files
Read and write 'Apache Parquet' files. Whole files are read with a single call, and larger ones can be opened to inspect their schema and read selected columns, row groups, or batches. Built on the bundled C library 'carquet', with no required R package dependencies.
