Below is a table containing all of the configurable options within the Structured File Lens. To see how to set config variables, see the Quick Start Guide or the full User Guide. With version 2.0 and beyond, fewer configuration is required to have your Lens operational, just setting the Lens Directory is enough. In addition, no configuration is required at startup as config can be updated on a running Lens.
To do this, similar simply call the endpoint /updateConfig?configEntry=<entry>&configValue=<value> where the entry the config item as seen below, and value is the new value you wish to set. Any configuration changed while the Lens is running can also be backed up and restored.
