[jira] [Created] (NIFI-1239) ConvertJSONToSQL should cache results from database resultset metadata

Mark Payne created NIFI-1239:
--------------------------------

             Summary: ConvertJSONToSQL should cache results from database resultset metadata
                 Key: NIFI-1239
                 URL: https://issues.apache.org/jira/browse/NIFI-1239
             Project: Apache NiFi
          Issue Type: Improvement
          Components: Extensions
            Reporter: Mark Payne
             Fix For: 0.5.0


Currently, when we convert JSON to SQL, we make calls to the database to determine the type of each column that we are converting. We should cache this information instead of calling to the database each time, as performance will be greatly improved. We should be sure not to cache indefinitely, though, as the schema could change.
