Graph in Memory

[Sushanth Vaddaram]

Hi,

We are using the following configuration where both the services dip and 
dipWithoutInf use the same databases

Now when dip_backup service which doesn't use reasoner updates the database, 
how can we tell the other service "dip" to infer from latest data and provide 
results from database rather than the memory where it created the graph 
previously
