Take JSON files and enrich them with data from an external database using NiFi. The data-flow mockup is the following:
Run prepare_test.py. This will create test files inside in directory and create external_db.db with some entries.
The NiFi template with the exercise resolution: data_enrichment.xml.
To implement this template you must replace replace_this_path with your working directory and replace_this_sql_driver_location with your sql driver location in data_enrichment.xml.
