[jira] [Created] (ARROW-14577) [C++] Enable fine grained IO for async IPC reader

Yue Ni created ARROW-14577:
------------------------------

             Summary: [C++] Enable fine grained IO for async IPC reader 
                 Key: ARROW-14577
                 URL: https://issues.apache.org/jira/browse/ARROW-14577
             Project: Apache Arrow
          Issue Type: Improvement
          Components: C++
    Affects Versions: 6.0.0
            Reporter: Yue Ni


The IPC reader operates at the granularity of an entire record batch; even if you're loading only a few columns, the entire record batch is read. ARROW-12683 partially addressed this issue by enabling this capability for sync read API, however, async read API still lacks of this capability.
