             Summary: Do Not Copy String When Flushing Dictionary
                 Key: ORC-831
                 URL: https://issues.apache.org/jira/browse/ORC-831
             Project: ORC
          Issue Type: Improvement
          Components: Java
            Reporter: David Mollitor
            Assignee: David Mollitor


{code:java|Title=StringBaseTreeWriter.java}
        if (useDictionaryEncoding) {
          rowOutput.write(dumpOrder[rows.get(i)]);
        } else {
          dictionary.getText(text, rows.get(i));
          directStreamOutput.write(text.getBytes(), 0, text.getLength());
          lengthOutput.write(text.getLength());
        }
{code}

The code to {{flush}} first loads (copies) the data into a {{Text}} object and then writes it to the direct stream.  Instead, pass the directStream to the dictionary and have it write directly to the stream instead of an intermediate {{Text}} object.
