hudi-io Module

This module contains classes that are I/O related, including common abstraction and APIs, readers and writers, etc.

HFile Reader

We implement our own HFile reader (org.apache.hudi.io.hfile.HFileReaderImpl) that functionally works on reading HBase HFiles in the Hudi metadata tables, based on the format described below.

HFile Format
