Hello All,

Working on creating custom module to read tag history. Created MyTagHistoryProvider class and implemented below interface.  
com.inductiveautomation.ignition.gateway.sqltags.history.TagHistoryProvider

startup() & shutdown() method executed successfully but createQuery method is not executed.  
startup() & shutdown() method executed during installation of module in ignition.  
Find the attached code and image for your reference.  
I did not know how to use createQuery method and its argument?  
Below is method signature for your reference.  
public HistoryQueryExecutor createQuery(List paths, QueryController controller)

Thanks & Regards,
