Our usage scenario is that when the hbase client and hfile are in the same machine(read local), we don't want to hbase client to communicate with regionserver and then send back the data. Serialization, deserialization and network transmission are time-consuming. The best way is hbase client can read local data directly. It's great if hbase client can consider these kinds of thing to improve scan performance. 在 2013-3-22，下午12:19， lars hofhansl 写道：
