Hello.
I have a Engine which is hosted in a optimal location for the people who
access it and this Engine manage multiple Datacenters, some close by and
some far away in terms of latency.
What is the maximum latency advised between the Engine and the hosts for
a healthy operation or that doesn't matter much as long the Engine can
always reach the hosts ?
Currently the maximum latency I have between Engine and Hosts is 110ms
and sometimes when there is a non-optimal route latency goes up to
170ms. Should I be concerned about this ?
Thanks
Fernando

Hello Fernando,
There is no known problem with such delay figures.
The heartbeat to the hosts is of several seconds.
Thanks,
Edy.

Fernando,
We use heartbeats to understand health of the connection. Potentially
you may see heartbeat exceeded exceptions
so you may want to increase vdsHeartbeatInSeconds. I would not change
it in advance but as you see the issue
and slowly increase the value.
Thanks,
Piotr
