Moving Data From Oracle to MongoDB : Bridging the Gap With JRuby

A homegrown ETL process for migrating data from Oracle to MongoDB based on JRuby chameleonic capabilities: a Ruby implementation integrating well in a Java environment:

Rather than having to re-map one database or the other in the other persistence technology to facilitate the ETL process (not DRY), JRuby allowed the two persistence technologies to interoperate. By utilizing JRuby’s powerful embedding capabilities, we were able to read data out of Oracle via Hibernate and write data to MongoDB via MongoMapper.
