Summary: Improve JSON Performance
Key: DRILL-1774
URL: https://issues.apache.org/jira/browse/DRILL-1774
Project: Apache Drill
Issue Type: Bug
Reporter: Jacques Nadeau
Assignee: Jacques Nadeau
There are multiple reasons that JSON performance is subpar. We need to update
the reader to do the following:
- Avoid double reading (for rewinding)
- Take advantage of Jackson interning/hashing of field names.
- Improve field selection behavior. (avoid object creation and multiple
traversals)
- Support filter pushdown
