Service reset while creating graph

#1

When I create a graph, I see that the tool stops GPE/GSE/RESETPP first and then starts them (see the log below). Two questions:

  • Why is this necessary?
  • What happens to running jobs/queries (most likely from other users) during the reset?

GSQL > create graph xgraph_1000()
Stopping GPE GSE RESTPP
Successfully stopped GPE GSE RESTPP in 0.003 seconds
Starting GPE GSE RESTPP
Successfully started GPE GSE RESTPP in 0.045 seconds
The graph xgraph_1000 is created.

#2

is this on 3.1? We need to sync up the meta data to the engine. Currently, the engine component will restart to refresh the meta data.

#3

Does this stopping/restarting interrupt other actively running jobs/queries?
