Have you tried https://docs.janusgraph.org/basics/transactions/#transaction-configuration ? It allows you to enable/disable storage.batch-loading per transaction. 

Hi Frederick,

This is a good question, but I have no answer. For myself, I have always take a fresh janusgraph instance if I wanted to change one of the properties!

Best wishes,    Marc

Which, if any, of the graph configuration properties are dynamic?

In particular, I would like to toggle `storage.batch-loading`.
