Antoine Pitrou commented on ARROW-7910:
---------------------------------------
Can probably add it to {{arrow/util/io_util.h}}.
Note that these days, you may want a multiple of page size - e.g. 16 kB or
more. Copying memory is so cheap that other costs (such as system calls,
bookkeeping...) might dominate.
> [C++] Provide function to query page size portably

> Page size is a useful default buffer size for buffered readers. Where should
> this property be attached? MemoryManager/Device?
> When this is available, it should probably be used to update
> {{parquet::DEFAULT_BUFFER_SIZE}} and {{arrow::datasets::ParquetFileFormat}}
