One Line of Python Code to Export a Property Graph to Flat Files

Last week I got a question on exporting a property graph to flat files in Python. Turns out that JPype can cause a bit of headache with "no matching overloads found."

An easy solution is as follows:

 JClass("oracle.pg.common.OraclePropertyGraphUtilsBase").exportFlatFiles(opg, "/tmp/g.opv", "/tmp/g.ove", False)

This solution is very cool in the sense that it works with any of the three supported property graph backend databases: Oracle Database 12.2.0.1, Oracle NoSQL Database, and Apache HBase.
