Glen Cao created HAWQ-565:
-----------------------------

             Summary: libhdfs3's support for async IO
                 Key: HAWQ-565
                 URL: https://issues.apache.org/jira/browse/HAWQ-565
             Project: Apache HAWQ
          Issue Type: Improvement
          Components: libhdfs
            Reporter: Glen Cao
            Assignee: Lei Chang


Q1: Does libhdfs3 support async IO operations? I.e., when libhdfs3 writes large files to HDFS, it doesn't need to block to wait for writes done. While files are being written to HDFS, apps using libhdfs3 could do other things meanwhile without using explicit multi-theading.

Q2: Any schedule to support ORC files?
