@Suhas_Kulkarni @neplatnyudaj refer the below post.

How to get the list of all variables from history?

Hey @sunnyorange, the HistoricVariableInstanceQuery also offers a list() method that queries the DB once and returns a list of HistoryVariableInstance objects. You could then process this list of variables in memory. Hope that helps you! Cheers, Tobias
