Are there any recommendations to reduce latency across nodes in AWS deployments ? Hosts are collocated in the same subnet.
Hi Colin, are you using a placement group for your nodes?https://www.vertica.com/docs/9.2.x/HTML/Content/Authoring/UsingVerticaOnAWS/CreatingAPlacementGroup.htm
Placement groups might block you later down the road from adding nodes to the cluster.
Usually it is enough to have all nodes in the the Availability Zone.
Are your projections properly organized?
What EBS Volume type are you using?
I switched recently to IO1 from ST1.
Yes, we are using placement group for the cluster. I am not too concerned about adding nodes later. I am wondering what tools could be use to monitor network latency on an ongoing basis.
