Pallavi Rao commented on FALCON-1059:
-------------------------------------

[~ajayyadava], your change handles the initial bootstrap only. We will also 
need to handle the cases where the lineage feature might be turned-off for a 
duration and turned back on. In such cases, we'll need to update the existing 
vertices/edges.

Also, we wanted to ensure bootstrapping the graph does not become a heavy 
operation (in terms of time) and shouldn't increase the server startup time.

> Lineage should support bootstrapping
