GArrowInputStream is a base class for input stream.
GArrowSeekableInputStream is a base class for input stream that supports random access.
GArrowBufferInputStream is a class to read data on buffer.
GArrowMemoryMappedInputStream is a class to read data in file by mapping the file on memory. It supports zero copy.
GArrowGIOInputStream is a class for GInputStream
based input
stream.
