class PARQUET_EXPORT ReaderProperties {
public:
/// Buffered stream reading allows the user to control the memory usage of
/// parquet readers. This ensure that all `RandomAccessFile::ReadAt` calls
are
/// wrapped in a buffered reader that uses a fix sized buffer (of size
/// `buffer_size()`) instead of the full size of the ReadAt.
///
/// The primary reason for this control knobs is for resource control and
not
/// performance.
bool is_buffered_stream_enabled() const { return buffered_stream_enabled_;
}
/// Enable buffered stream reading.
void enable_buffered_stream() { buffered_stream_enabled_ = true; }
/// Disable buffered stream reading.
void disable_buffered_stream() { buffered_stream_enabled_ = false; }
