------------------------------------
Summary: JDBC should default to getting complex data as JSON
Key: DRILL-2188
URL: https://issues.apache.org/jira/browse/DRILL-2188
Project: Apache Drill
Issue Type: Improvement
Components: Client - JDBC
Reporter: Parth Chandra
Assignee: Daniel Barclay (Drill/MapR)
Priority: Minor
Fix For: 0.8.0
Currently the ODBC driver gets complex data as a JSON string while the JDBC
driver gets complex data as a complex type which it then converts to JSON. The
conversion to JSON in the JDBC path uses an expensive method that also consumes
excessive amounts of CPU.
Since client applications are unable to consume complex data, the default
should be to get JSON data and there should be a client side setting (session
paramater) to revert to getting complex data.
