Summary: ORCMapredRecordWriter enlarge columnVector with factors
when child array size is not large enough
Key: ORC-638
URL: https://issues.apache.org/jira/browse/ORC-638
Project: ORC
Issue Type: Improvement
Reporter: Lei Sun
Assignee: Lei Sun
Currently the ensureSize() method is called with the targetSize being current
childCount. The downside of it: It could keep triggering resize everytime when
new list-as-a-row being added and slow down the write throughput.
