The current data exporter functionality has the following design limitations

Database Configuration

• QT_BREAKDOWN_PATH table configuration for Request/Export file XML definition support is limited to SQL statements only.
• HIVE_CELL_PARAMS edu.harvard.i2b2.crc.exportcsv.defaultseperator value parameter overrides the file type parameter set in edu.harvard.i2b2.crc.exportcsv.filename value column parameter 

           Example default separator value : '|'

                          file type value: demograhics.csv

                           export file generated: demographics.csv with '|' separator

Export File generation

• Currently, the export file generation location must be accessible to the application Server hosting the i2b2 application
• Requester email is configurable to be generated as a txt file in the data export file directory The data Manager will be required to manually copy the file content into an email and send it to the data request User.
• The default export file location and format should be set in the HIVE_CELL_PARAMS and requires a restart of the wildfly for the changes to take effect.
