Workflow can be defined to run in-memory. Such workflows produce less persistent data and hence require less disk space, both on the file system and the database.
  
 
	 
		For more information on running workflows in-memory, refer to 
		  TIBCO MDM Workflow Reference.
		
	  
 
	 Failover considerations
		
		It is recommended that only smaller workflows be run in-memory and not long running workflows, since in case of failover for an in-memory workflow, the entire workflow is re-executed. For more information on workflow failover, refer to 
		  TIBCO MDM Workflow Reference.
