Wes McKinney created ARROW-410:
----------------------------------
Summary: [C++] Add Flush method to arrow::io::OutputStream
Key: ARROW-410
URL: https://issues.apache.org/jira/browse/ARROW-410
Project: Apache Arrow
Issue Type: New Feature
Components: C++
Reporter: Wes McKinney
Some output sinks have a flush() method separate from write(...). Rather than
flushing all writes, we can leave this up to the implementation, and have a
default no-op Flush implementation. This came up during ARROW-404 (ran into
test failure with unflushed writes, because the Java HDFS client does not
auto-flush)
